Question: Find the x-values for which f'(x)=0 in the given interval. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.)f'(x)=6x224x

Find the x-values for which f'(x)=0 in the given interval. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.)f'(x)=6x224x 30=0x=1,5Note that since f(x) is defined on a closed interval, f'(x) cannot exist at the endpoints of the interval because the definition of the derivative at a point requires the existence of a two-sided limit. Find the x-values for which f'(x) is undefined in the given interval. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.)f'(x) is undefined when x = DNE .Thus, the potential extreme points of f(x) in the given interval are x = 1,5
