Here "extreme value" refers to either a "maximum" or a "minimum."
Find the derivative of the given function and solve for the critical value (or values).
Plot these on the x-axis of a set of coordinate axes.
This will definie several intervals on the x-axis.
Choose a representative number from each such interval. Plug that number into the derivative of f(x). Is the result + or - ?
Know what to do next?

no @mathmale

Are you familiar with derivative? @xedwinvf67

no sir i dont

Ok you do know what \(x^2\) looks like, right?
What is extreme values for \(x^2\)?
