The function is odd because f(–x) = –f(x).
What is a function?
A function is a special form of relation where each input has exactly one output. In other words, for each input value, the function returns exactly one value. A relation rather than a function is depicted in the above graph because one is mapped to two different values. However, if one were instead mapped to a single value, the relationship described above would change into a function. Furthermore, output values could match input values exactly.
Odd function means f(-x) = -f(x)
and Even function means f(-x) = f(x)
Here the given function f(x) = 4[tex]x^{5}[/tex]
Put, x = -x
We have f(-x) = 4 ([tex](-x^){5}[/tex])
5 is an odd number so we will get a negative value. So f(-x) = -f(x)
Hence, The function is odd because f(–x) = –f(x).

You have learned about quadratic and linear function in earlier grades. Explain in a variety of ways how you can distinguish the exponential function
f(x)=2^x
from the quadratic function
f(x) = x^2
and linear function
f(x) = 2x
. (Hint: compare the rate of change using finite differences in tables of values, and identify a constant ratio in the table of values).
We can distinguish between the linear, exponential function and quadratic functions graphically. The graph of the functions is as follows:
linear function f(x) = 2x will be straight line,
for exponential function f(x) = 2^x will rise or fall quickly in one direction
and for quadratic function f(x) = x^2 will be a parabola.
What is an exponential function?An exponential function is a type of mathematical function expressed in the form f(x) = a^x. where "x" is a variable and "a" is a constant called the base of the function, which must be greater than 0. The most commonly used exponential base is the transcendental number e, which is approximately equal to 2.71828. The exponential function is defined by the formula f(x) = ax. where the input variable x is displayed as an exponent. Exponential curves grow or fall exponentially. A quantity that increases or decreases at a regular rate should exhibit either an exponential increase or an exponential decay.To learn more about exponential function from the given link :

The length of a rectangle is 3 m longer than its width. If the perimeter of the rectangle is 36 m, find its length and width.
Group of answer choices
width = 7.5 m, length = 10.5 m
width = 16.5 m, length = 13.5 m
width = 16.5 m, length = 19.5 m
width = 7.5 m, length = 4.5 m
The length and width of the rectangle are (a) width = 7.5 m, length = 10.5 m
Let the width (W) = x
Length (L) = x+3
According to question,
Perimeter = 36m
Perimeter = 2(L + W)
36 = 2(x+3+x)
36 / 2 = 2x + 3
18 = 2x + 3
18 - 3 = 2x

Question:
Draw the graphs described below and answer the question for each.
A. Draw the graph of a line with an undefined slope. Write the equation of the line you drew.
B. If you wrote the first letter of your LAST NAME (upper-case letter) on a coordinate plane, would it be a function? Make a sketch and provide an explanation as to how you determined whether it is a function or not.
Solution:
A.
Remember that any line that has an undefined slope is a vertical line, that has no y-intercept. Therefore the equation of a line with an undefined slope is x = a, where a = x-intercept.
we can conclude that the correct answer is:
According to this information, we can take the following equation for a line with an undefined slope:
[tex]x=5[/tex]and its graph would be:
B. Remember that a simple visual way to determine if a particular graph is a function is by imagining vertical lines passing through it. If the vertical line touches more than once, it is not a function.

Find the axis of symmetry for the parabola that has the points (-2.5, 3) and (-4.5, 3) Justify your answer
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves.
The axis of symmetry always passes through the vertex of the parabola.
The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
A general graph of a vertical parabola is shown below:
Note there are two points x1 and x2 that have the same y-coordinate. These points are equidistant from the axis of symmetry. So, if we are given the coordinates of the points, we can find the axis of symmetry by calculating their average.
We are given the points (-2.5, 3) and (-4.5, 3).
Since they have the same y-coordinate, we calculate the average of the x-coordinates as follows:
[tex]x_s=\frac{-2.5-4.5}{2}=-3.5[/tex]Thus, the axis of symmetry of the parabola is x = -3.5
hi, I'm supposed to write a exponential equation for the graph but I'm not sure how to do it

To determine the type of function, we would compare the y values. If the ratio of consecutive y values is the same, then the function is exponential. We have
2/1 = 4/2 = 8/4 = 2
Thus, it is an exponential function. The general formula for an exponential function is
y = ab^x
We would find a and b
Substituting x = 0 and y = 1 into the formula, we have
1 = ab^0
1 = a
Substituting x = 1 and y = 2 into the formula, we have
2 = ab^1
2 = ab
Substituting a = 1 into 2 = ab, then
2 = 1 * b = b
By substituting a = 1 and b = 2 into the original formula, the equation would be
y = 2^x
in a video store,a DVD that usually sells for $15 is marked 10% OFF that price. How much does the DVD cost now that it's on sale?
Answer
The cost of the DVD now that it's on sale will be $13.5
Explanation
DVD actual price = $15
10% off the price will be (10/100 x $15) = $1.5
The selling price of the DVD now will be $(15 - 1.5) = $13.5
∴ The cost of the DVD now that it's on sale will be $13.5
1 2 What is the probability of an event that is certain?
The probability of an event is a number describing the chance that the event will happen. An event that is certain to happen has a probability of 1. An event that cannot possibly happen has a probability of zero. If there is a chance that an event will happen, then its probability is between zero and 1.
An event that is certain to happen has a probability of 1.
Assume the annual day care cost per child is normally distributed with a mean of $8000 and a standard deviation of $1000. What percent of day care costs are more than $7100 annually?Click here to view page 1 of the standard normal distribution tableClick here to view page 2 of the standard normal distribution table,% (Round to two decimal places as needed.)
Answer:
81.59%
Explanation:
To find the percentage, we first need to standardize $7100. To standardize, we subtract the mean and then divide by the standard deviation. So, $7100 is equivalent to:
[tex]\begin{gathered} z=\frac{x-\operatorname{mean}}{std\text{ deviation}} \\ z=\frac{7100-8000}{1000}=-0.9 \end{gathered}[/tex]Now, the percentage of day care costs that are more than $7100 is equivalent to the probability that z is greater than -0.9, so:
P(x > $7100) = P(z > -0.9)
Finally, we can use the standard normal distribution table to get:
P(z > -0.9) = 0.8159
So, the answer is 81.59%

To qualify an assertion, it is not necessary for the statement to be true. An assertion is an emphatic declaration made as part of an argument or as if it is to be understood as a statement of fact. To assert is to make a strong statement. So when someone makes an assertion, they aren't just experimenting with a new idea; they truly believe it.
