WebTo obtain the extrema of a function in a closed interval, we must first find the critical numbers of f f f in the interval (a, b) (a,b) (a, b), and then evaluate the function at the critical numbers.We then evaluate the function at the endpoints as well. The greatest of the various values will be the maximum and the least of them will be the minimum.
WebLet’s find the absolute extrema of f ( x) = x3 – 12 x + 23 on the interval [-5, 3].
