Can someone help me 5-13 please?

 see below

Step-by-step explanation:

#5 - 7: Domain are the x-values and Range are the y-values.

5) Coordinates are: (-2, 3), (0, 3), (2, 3), (4, 3)

   Domain: x = {3}         Range: y = {-2, 0, 2, 4}

6) All points on the curve between -4 and 2 (x-values) & 3 and 6 (y-values). Endpoints are included.

Domain: -4 ≤ x ≤ 2         Range: 3 ≤ y ≤ 6

7) All points on the curve between 2 and 7 (x-values) & 1 and 6 (y-values). Endpoints are not included.

Domain: 2 < x < 7         Range: 1 < y < 6

#8 - 11: Choose points for x. Plug them into the equation to solve for y.

To graph the equation, plot the points and connect the dots.

8)                  x         y = x

                   -2             -2

                    -1             -1

                     0             0

                     1              1

                     2             2

9)                  x         y = 2x+1

                   -2             2(-2)+1 = -3

                    -1             2(-1)+1 =  -1

                     0            2(-0)+1 =  1

                     1             2(1)+1 =   3

                     2            2(2)+1 =  5

Note:

You are allowed a maximum of 3 questions. I answered 5 questions. If you need help with the rest of your homework, you will need to create another post.
