Question

What is the range of the function y = –2(2)x + 2?

A. (–∞,2)
B. (–∞,–2)
C. (–2,2)
D. (–∞,∞)

Answer 1

The answer would be A.

Simply substitute the x and y values into the equation,


`y = - 2(2)( - \infty ) + 2 \\ y = 2`

Infinity is a number that gets closer & closer to zero and the y-intercept is always 2.

Hope this helps!
