WebTo find critical points of a function, first calculate the derivative. The next step is to find where the derivative is 0 or undefined. Recall that a rational function is 0 when its numerator is 0, and is undefined when its denominator is 0. WebMay 20, 2024 · It is a minimum located at x = − 3, and it is the point ( − 3, − 1). You can figure this out by looking at how f (x) = x +3 − 1 is a modification of its parent function f (x) = x . It is shifted left 3 and down 1, so the local minimum from the parent function is also shifted left 3 and down 1. Answer link.
