Question 8, 6.2.49
Part 2 of 6
The function $f(x)=x^{2}-2, x \geq 0$ is one-to-one.
(a) Find the inverse of $f$ and check the answer.
(b) Find the domain and the range of $f$ and $f^{-1}$.
(c) Graph $f, f^{-1}$, and $y=x$ on the same coordinate axes.
(a) $f^{-1}(x)=\sqrt{x+2}$
(Simplify your answer. Use integers or fractions for any numbers in the expression.)
(b) Find the domain of f . Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A. The domain is $\{x \mid x \leq$ $\square$
B. The domain is $\{x \mid x \neq$ $\square$
C. The domain is $\{x \mid x \geq$ $\square$
D. The domain is the set of all real number
