Suppose f(x) is a function such that x=1 and x=4 are its only critical numbers, and f′(x)=x−3(x−1)(x−4)2​ and f(x) is defined for all values of x, except at x=3. Which statement best describes what is happening at x=1 ? f(x) has a local minimum value at x=1. f(x) has a local maximum value at x=1. This question cannot be answered without more information about f(x). f(x) has both a local maximum value and a local minimum value at x=1. f(x) has neither a local maximum value nor a local minimum value at x=1.
