Answer:
{-3, 29, 21, 33}
Explanation:
Substitute the x values (domain) to find y, do this for all x's-
f(x) = 6(-2) + 9 = -3
f(x) = 6(0) + 9 = 9
f(x) = 6(2) + 9 = 21
f(x) = 6(4) + 9 = 33
Range-
Take the y values and arrange it from least to greatest (this matters and your teacher may most likely count it wrong if you do not put it in increasing order)
{-3, 29, 21, 33}
