The first step in finding a function’s local extrema is to find its critical numbers (the x-values of the critical points).You then use the First Derivative Test. This test is based on the Nobel-prize-caliber ideas that as you go over the top of a hill, first you go up and then you go down, and that when you drive into and out of a valley, you go down and then up.

Another huge thing in Calculus is finding relative extrema. Check out this graph: The tops of the mountains are relative maximums because they are the highest points in their little neighborhoods (relative to the points right around them):. Suppose you're in a roomful of people (like your classroom.)

Section 3-3 : Relative Minimums and Maximums. ... So, once we have all the critical points in hand all we will need to do is test these points to see if they are relative extrema or not. To determine if a critical point is a relative extrema (and in fact to determine if it is a minimum or a maximum) we can use the following fact. ...

How to Find Local Extrema with the Second Derivative Test. The Second Derivative Test is based on two prize-winning ideas: First, that at the crest of a hill, a road has a hump shape — in other words, it’s curving down or concave down. And second, at the bottom of a valley, a road is cup-shaped, so it’s curving up or concave up. ...

Another drawback to the Second Derivative Test is that for some functions, the second derivative is difficult or tedious to find. As with the previous situations, revert back to the First Derivative Test to determine any local extrema. Example 1: Find any local extrema of f(x) = x 4 − 8 x 2 using the Second Derivative Test.
