Consider the following function. $f(x) = \sqrt{x - 7}$, $x > 7$ What is the domain of $f$? (Enter your answer using interval notation.) Is $f$ continuous on this domain? Yes No Find $f'(x)$. $f'(x) = $ Does $f$ have an inverse function? Yes No Consider the real number $a = 3$. For what value of $x$ does $f(x) = 3$? (If an answer does not exist, enter DNE.) $x = $ Determine the value of $f^{-1}(3)$, if it exists. (If an answer does not exist, enter DNE.) $f^{-1}(3) = $ Use the function $f$ and the real number $a = 3$ to find $(f^{-1})'(3)$, if it exists. (If an answer does not exist, enter DNE.) $(f^{-1})'(3) = $
