Step 1
To do this, we need to find where the derivative of the function is equal to zero or undefined. The derivative of 5x on the interval [0,9] is simply 5. The derivative of x^2 is 2x. The derivative of 9 is 0 since it is a constant. So, the critical points occur Show more…

Find the absolute maximum and absolute minimum (if they exist) of the given function on the specified interval. f(x) = x 5 − 5x 4 + 1; 0 ≤ x ≤ 5
Ivan K.
Find the absolute maximum and minimum values of each function, if they exist, over the indicated interval. Also indicate the $x$ -value at which each extremum occurs. When no interval is specified, is specified, use the real line, $(-\infty, \infty)$. $$f(x)=9-5 x ;[-2,3)$$
