Question

Solve y=3x+2 if the domain is {2,3,-4} please help?

Answer 1

Plug the domain in for X and you will get the range (y)

y= 3x+2

y=3(2)+2    y = 8

y=3(3)+2   y = 11

y=3(-4)+2   y = -10

Answer 2

y = 3x + 2

Domain: {2, 3, -4}

Range is the solution set for the domain.

y = 3(2) + 2 = 6 + 2 = 8

y = 3(3) + 2 = 9 + 2 = 11

y = 3(-4) + 2 = -12 + 2 = -10

Solution: Range: {8, 11, -10}
