Let the function $f$ be differentiable on an interval $I$ containing c. If $f$ has a maximum value at $x=c$, show that $-f$ has a minimum value at $x=c$.
Suppose a function f(x) is differentiable everywhere and has a local minimum at x=c. If f'(x)<0 when x<c, and f'(x)>0 when x>c, then by the Global Interval Method we know x=c is a local maximum an absolute minimum a local minimum an absolute maximum
