Question

Let f(x) = x^2-4 what is the range

Answer 1

Range: [-4, ∞), y

Explanation:

It helps if you graph the function to better understand what the range is.

In interval and set-builder notation, the range is:

[-4, ∞), y ≥ -4

This is knowing that the Domain is:

(-∞, ∞), x

Answer 2

Range: [−4,∞)

Explanation:
