concavity). If f’(x) = 0 and f’’(x) > 0, x is a minimum point If f’(x) = 0 and f’’(x) < 0, x is a maximum point If f’(x) = 0 and f’’(x) =0, x is an inflection point By using the first derivative test and the candidates’ test, we can precisely determine where the minima and maxima of a function are,
