Question

The domain of t(x) = -3.8x - 4.2 is {-3, -1.4, 0, 8}. What is the range?

Answer 1

plug each x into your equation and the answer for each is your range (y-value)

I'll do one
-3.8x - 4.2 for x = -3
y = -3.8(-3) - 4.2
y = 11.4 - 4.2
y = 7.2

so y = 7.2 is incl. in the range
repeat for each x value

Answer 2
