Consider a continuous function J (x). The function has critical points at x = U, and shows the critical points of the function and the sign off" (x) on each critical point. At which value(s) of x are local minima guaranteed to occur? Critical Point Sign off" (x) at Critical Point -6 + -1 0 0 5 + Select all that apply: 0 -6 0 -1 0 0 0 5 The function is not guaranteed to have a local minimum
