I'm in middle of an exam. Please help asap

iMath 1 Gmail Youtube Suppose that f (x) = 923 - 23 -3. (A) Find all critical numbers of f. If there are no critical numbers, enter 'NONE' Critical numbers = (B) Use Interval notation to Indicate where f (x) Is Increasing. Note: Use 'INF' for co, '-INF' for -co, 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'. values of local maxima = (E) List the x-coordinates of all local minima of f. If there are no local minima, enter 'NONE'. values of local minima = (F) Use interval notation to indicate where f(2) is concave up. Concave up: (G) Use interval notation to indicate where f (r ) is concave down. Concave down: (H)List the x values of all inflection points of f. If there are no inflection points, enter 'NONE'. values of inflection points = (1) Use all of the preceding information to sketch a graph of f. When you're finished, enter a "1" in the box below.
