Find the absolute maximum and absolute minimum values of f on the given interval. f(x)=x+(9/x) interval=(0.2 , 12)
You need to remember Fermat's theorem that tells you about the relation between the critical points and extrema of a function.
You may find the critical points of a function solving the equation `f'(x)=0` , hence you need to differentiate the function with respect to x to find the equation of `f'(x)` such that:
