Practice similar Use a graph below of f(x) = 3e-84 to estimate the x-values of any critical points and inflection points of f(a). critical points (enter as a comma-separated list): x = inflection points (enter as a comma-separated list): x = Next, use derivatives to find the x-values of any critical points and inflection points exactly. critical points (enter as a comma-separated list): x = inflection points (enter as a comma-separated list): x =2 .
