Question
Find the absolute maximum and minimum, if either exists, for each function on the indicated intervals.$f(x)=x^{4}-4 x^{3}+5$(A) [-1,2](B) [0,4](C) [-1,1]
Step 1
We do this by taking the derivative of the function and setting it equal to zero. The derivative of $f(x)=x^{4}-4 x^{3}+5$ is $f'(x)=4x^{3}-12x^{2}$. Show more…
