Suppose that f(x)=3x2ln(x),x>0. (A) List all critical numbers of f. If there are no critical values, enter 'NONE'. critical numbers =e21​1​ (B) Use interval notation to indicate where,(w, is increasing. Note: Use 'INF' for ∞, '-INF' for −∞, and use 'U' for the union symbol. Increasing: (C) Use interval notation to indicate where f(x) is decreasing. Decreasing: (D) List the x-coordinates of all local maxima of f. If there are no local maxima, enter 'NONE'. x values of local maxima = (E) List the x-coordinates of all local minima of f. If there are no local minima, enter 'NONE'. x values of local minima = (F) Use interval notation to indicate where f(x) is concave up. Concave up: (G) Use interval notation to indicate where f(x) is concave down. Concave down: (H) List the x values of all inflection points of f. If there are no inflection points, enter 'NONE'. x values of inflection points =
