Sam plotted the function f (x)=(x - 2)^2 + 3 and its inverse. He determined that the equation for the inverse is f (x)=V2 – 3+2.
How must Sam restrict one of the functions so that the graphs reflect the inverse
relationship?

A. Sam must restrict the domain of f-1(x) to x is greater or equal to 2

B. Sam must restrict the domain of f(x) to x is greater than it equal to 2

C. Sam must restrict the domain of f-1(x) to x is greater than or equal to 3

D. Sam must restrict the domain of f(x) to x is great than or equal to 3
