Question

What is the range of y = 5x -2 if the domain is {-3, -1, 0, 1, 3}?
Answer

{-13, -3, 2, 3, 13}

{12, 3, 0, 3, 13}

{-17, -7, -2, 3, 13}

Answer 1

y = 5x - 2

when x = 0

y = -2

when x = -3 , y = 5*-3 - 2 = -15-2 = -17

when x = 3

y = 5*3 - 2 = 15 - 2 = 13

therefore , answer is the third option
