Question

Given the domain values { -2, 0, 2 }, find the range values for the function y = 3x – 2.

{ -8, -2, 4 }

{ 8, -2, 4 }

{ 12, 0, -12 }

none of the above

Answer 1

Domain values = values of x
Sub the domain values in the equation to get the range.

At x = -2, y =?
At x = 0, y =?
At x = 2, y =?
