Question

Match each function with its range.

Answer 1

I will not do the whole thing for you but I can help you get started

the key is to remember that the output of sqrt(anything) must be 0 or greater. (only considering real numbers for this problem)

so let's use the first problem as an example.

f(x) = -sqrt(x)

if it was just sqrt(x), then the range would be y ≥ 0, since square root only outputs 0 or greater. however, since there's a negative sign in front, it flips around and becomes y ≤ 0

can you try applying this kind of logic to the rest of the problems? I'm here to help out if you get stuck
