The range of the function g(x) = x² + 2 for the given domain is found to be {27,3,25,6,102}.
What is the difference between domain and range in function?The domain of a function is the set of values that may be plugged into it. This set contains the x values in a function like f. (x). A function's range is the set of values that the function can take. This is the collection of values that the function returns when we enter an x value.
How do you find domain and range in the absence of numbers?To determine the domain of a function, f(x), determine which values of x cause f(x) to be undefined/not real. The usual procedure for determining range is to find x in terms of f(x) and then locate values of f(x) for which x is not defined.
Given:
g(x) = x² + 2
Domain of the function: {-5, -1, 0, 2, 10}
We need to find the range.
Let us substitute x = -5 in g(x)
g(-5) = (-5)² + 2
= 27
g(-1) = (-1)² + 2
= 3
g(0) = (0)² +(-5)²
= 25
g(2) = (2)² + 2
=6
g(10) = (10)² + 2
= 102
Therefore, the range of the given function g(x) = x² + 2 for a given domain is found to be {27,3,25,6,102}.

[tex]Ax+By=C[/tex]But since the x-coordinates of the points are equal, then the formula for slope is not applicable (the denominator equals 0).
In this case, we say that the slope is undefined (the line is vertical).

The midpoint of two points of coordinates (x1, y1) and (x2, y2) has the following coordinates
[tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}_{})[/tex]Then, the midpoint can be calculated replacing (x1, y1) = (3, 3) and (x2, y2) = (-9, 2), so

Consider the equation. y=1/4(x-5)^2-3Vertex (5,-3)The next step in graphing a parabola is to find points that will determine the shape of the curve. Find the point on the graph of this parabola that has the X-coordinates X=3.
We have the equation:
[tex]y=\frac{1}{4}(x-5)^2-3[/tex]This is a parabola expressed in vertex form, where the vertex is (h,k) = (5,-3).
We have to graph the parabola. To do that we need another point, as we already know the vertex and, therefore, the axis of symmetry (x = 5).
We can find another point by giving a value to x and calculating y.
For example, with x = 3 we get:
[tex]\begin{gathered} y(3)=\frac{1}{4}(3-5)^2-3 \\ y(3)=\frac{1}{4}(-2)^2-3 \\ y(3)=\frac{1}{4}\cdot4-3 \\ y(3)=1-3 \\ y(3)=-2 \end{gathered}[/tex]The point that belongs to the parabola when x = 3 is (3, -2).
Then, we can graph the two points and draw the parabola as:
Because of the symmetry at x = 5, we also know that two units to the right, at x = 7, we will have the same value of y that we have for x = 3.
With at least 3 points, we can graph a parabola.
The actual graph is:
If we want to add more precision to our graph, we can calculate more points that belong to the parabola.
For example, at the other side of the vertex, we can calculate the value of y for x = 6:
[tex]\begin{gathered} y(6)=\frac{1}{4}(6-5)^2-3 \\ y(6)=\frac{1}{4}(1)^2-3^{} \\ y(6)=\frac{1}{4}-3 \\ y(6)=\frac{1}{4}-\frac{12}{4}^{} \\ y(6)=-\frac{11}{4}=-2.75 \end{gathered}[/tex]We can add this to the plot as:
We have to aproximate the position of y as the grid only shows integers and y = -2.75.
Answer:
The points in the parabola are (5,-3), (3,-2) and (6,-2.75). We need at least 3 points to plot a parabola.

Percentage rise in patients from 2004 to 2014 = 7.59%
Explanation:The number of patients in 2004 = 39080
The number of patients in 2014 = 42045
Increase in the number of patients = (The number of patients in 2014) - (The number of patients in 2004)
Rise in the number of patients = 42045 - 39080
Rise in the number of patients = 2965
[tex]\begin{gathered} \text{Percentage rise in patients = }\frac{\text{Rise in the number of patients}}{\text{Number of patients in 2004}}\times100 \\ Percentage\text{ rise in patients = }\frac{2965}{39080}\times100 \\ \text{Percentage rise in patients = }7.59\text{ \%} \end{gathered}[/tex]Percentage rise in patients from 2004 to 2014 = 7.59%

A company is going to make a storage container with sheet steel walls. The container will be in the shape of a rectangular prism, as shown below. If the sheet steel costs $30 for each square meter, how much will the sheet steel cost in total?
ANSWER
$3060
EXPLANATION
Each steel sheet used for the prism costs $30 per square meter.
To find the total cost of the sheet, we have to find the surface area of the rectangular prism. Then we multiply the surface area by the cost per square meter.
The surface area of a rectangular prism is:
[tex]\begin{gathered} A\text{ = 2(}wh\text{ + wl + hl)} \\ \text{where h = height} \\ w\text{ = width} \\ l\text{ = length} \end{gathered}[/tex]From the diagram:
l = 7 m ; w = 3 m ; height = 3 m
Therefore, the surface area of the prism is:
[tex]\begin{gathered} A\text{ = 2\lbrack(3 }\cdot\text{ 3) + (3 }\cdot\text{ 7) + (3 }\cdot\text{ 7)\rbrack} \\ A\text{ = 2(9 + 21 + 21)} \\ A\text{ = 2(51)} \\ A\text{ = 102 square meters} \end{gathered}[/tex]Now, we multiply by the cost per square meter:
[tex]\begin{gathered} C\text{ = 102 }\cdot\text{ 30} \\ C\text{ = \$3060} \end{gathered}[/tex]That is the total cost of the steel sheet.
