Answer 2

Answer:

D.

Step-by-step explanation:

Domains refer to the x values, while range refers to the y values. You will need to solve 3 equations.

1. 12(-4)+6y=24

  -48 + 6y= 24

           6y=72

             y=12

2. 12(0) +6y = 24

             6y=24

               y=4

3. 12(5) + 6y = 24

    60 + 6y = 24

            6y = -36

              y=-6

The range is {12,4,-6}, D
