Question 975181: Suppose f(x)=x^2 over the domain of f, then:
(A)f^(-1) (x)=√x
(B)f^(-1) (x)=x/2
(C)f^(-1) (x)=-x^2
(D)f^(-1) (x) does not exist
(E) none of the above

if , then inverse will be:
.......recall that , so we have
...........swap and
.......solve for
, your inverse


so, your answer is: (A)
