Which equation is the inverse of y=x2+16

Step-by-step explanation:

let : y = x² + 16

calculate : x

x² = y - 16

x exist : y -16 ≥ 0

x = √(y - 16)    or x =  - √(y - 16 )

conclusion :  

if : x ≥ 0    the inverse of f(x) is : g(x) = √(x - 16)

if : x ≤ 0    the inverse of f(x) is : h(x) =  - √(x - 16)
