Consider the function $f(x) = 2\sqrt{x}$ over the interval $[1, 81]$. Complete parts a and b below.
a. Determine whether the Mean Value Theorem applies to the above function on the given interval.
$\circ$ Yes
$\circ$ No
b. If so, find or approximate the point(s) that is (are) guaranteed to exist by the Mean Value Theorem. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
$\circ$ A. The point(s) guaranteed to exist is (are) x =
(Simplify your answer. Type an exact answer, using radicals as needed. Use a comma to separate answers as needed.)
$\circ$ B. The Mean Value Theorem does not apply to $f(x)$.
