Maggie claims that if you restrict the domain of function f(x)=x2βˆ’4 to be xβ‰₯βˆ’2, then the function is invertible and the inverse function is fβˆ’1(x)=x+4βˆ’βˆ’βˆ’βˆ’βˆ’βˆš. 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 xβ‰₯βˆ’2 the function is invertible.

B
The claim is incorrect because in order for f(x) to be invertible and its inverse to be fβˆ’1(x)=x+4βˆ’βˆ’βˆ’βˆ’βˆ’βˆš the domain must be restricted to xβ‰₯0.

C
The claim is incorrect because in order for f(x) to be invertible and its inverse to be fβˆ’1(x)=x+4βˆ’βˆ’βˆ’βˆ’βˆ’βˆš the domain must be restricted to xβ‰₯βˆ’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.
