How To Find Relative Extrema From An Equation. (don’t forget, though, that not all critical points are necessarily local extrema.) the first step in finding a. (relative extrema (maxs & mins) are sometimes called local extrema.) other than just pointing these things out on the graph, we have a very specific way to write them out.
All local maximums and minimums on a function’s graph — called local extrema — occur at critical points of the function (where the derivative is zero or undefined). Candidates for extreme value points can also be returned.

Evaluatefxx, fyy, and fxy at the critical points. F ‘(x) = 2×2(2x −3) if we set f ‘(x) = 0, we find two possible extrema at x = 0 and x = 3 2.
