The critical values of the function are x = 0 and x = 64
The critical values of a function f(x) are the values of x for which f'(x) = 0.
Given,
f(x) =
The derivative is found as follows, applying the quotient rule:
f'(x) =
=
The zeros of the function are the zeros of the numerator, thus:
x - 64 = 0------------->x = 64
The critical values are x = 0 and x = 64
