Find the inverse of the function

Answer:
Step-by-step explanation:
g(x) = (x-2)² -7
let : g(x) = y
y = (x-2)² -7 solve for : x
(x-2)² = y - 7
if : y - 7 ≥ 0
x - 2 = √( y - 7) or x - 2 = - √( y - 7)
x = 2+√( y - 7) or x = 2 - √( y - 7)
the inverse of the function g is :
f(x) = 2+√( x - 7)
or :
f(x) = 2 - √( x - 7
