Maggie claims that if you restrict the domain of function f(x)=x2−4 to be x≥−2, then the function is invertible and the inverse function is f−1(x)=x+4−−−−−√. Which statement provides a correct analysis of Maggie's claim?
A
The claim is correct because when the domain of f(x) is restricted to x≥−2 the function is invertible.

B
The claim is incorrect because in order for f(x) to be invertible and its inverse to be f−1(x)=x+4−−−−−√ the domain must be restricted to x≥0.

C
The claim is incorrect because in order for f(x) to be invertible and its inverse to be f−1(x)=x+4−−−−−√ the domain must be restricted to x≥−4.

D
The claim is incorrect because there is not a domain restriction that can be applied to f(x) to make the function invertible.
