Answer:
The inverse of this function is a parabola that has been rotated 90 degrees clockwise, with it's vertex at point 1, 0.
So it's domain is x ≥ 1
And it's range is y ≥ -2
Step-by-step explanation:
Given:
f(x) = (x + 2)² - 1
First we find the inverse:
x = (f(x) + 2)² - 1
x - 1 = (f(x) + 2)²
√(x - 1) = f(x) + 2
f(x) = -2 ± √(x - 1)
