Consider the graph of f(x) given below. (a) Analyzing the graph, if g(x)=f(x), then g is decreasing for x (b) Analyzing the graph, if h(x)=f(x), then h is decreasing for x Note: Input U, infinity, and -infinity for union, , and , respectively. Find all critical numbers c of f(x)=(2x8)e6x. c= Note: If there is more than one critical number, separate them by a comma. You have attempted this problem 0 times. You have 3 attempts remaining. Consider the function f(x)=6x3+18x2+54x8 (a) f is increasing for x (b) f is decreasing for x (c) The local maxima of f occur at x= (d) The local minima of f occur at x= Note: Input U, infinity, and -infinity for union, , and , respectively. If there are multiple answers, separate them by commas. If there is no answer, input none
