Answer:

Hope it helps

Step-by-step explanation:

To find the inverse of f(x), first you switch x and y

f(x) = √x - 2 <=> y =√x - 2 <=> x = √y - 2 <=> you solve for y <=>

√y = x + 2 <=> now you need to get rid of the root <=>(√y)² = (x+2)²

<=> y = (x+2)²

(x+2)² can also be written as x²+4x + 4

but however you write it is okay. And yes it is a function.
