31 f(I) = 12 - 49 (A) List all critical numbers of f. If there are no critical numbers, enter 'NONE'. Critical numbers = (7,-7) B) Use interval notation to indicate where f(r) is decreasing. Note: Use 'INF' for oo, '-INF' for -co, and use 'U' for the union symbol. Decreasing: (-infinity -7) (C)List the x-values of all local maxima of f. If there are no local maxima, enter 'NONE'. I values of local maxima = -7 (D) List the r-values of all local minima of f. If there are no local minima, enter 'NONE'. values of local minima = 7 (E) List the x values of all inflection points of f. If there are no inflection points, enter 'NONE'. Inflection points = -7 (F) Use interval notation to indicate where f(r) is concave up. Concave up: (7, infinity ) (G) Use interval notation to indicate where f(r) is concave down. Concave down: (-infinity ,-7) (H) List all horizontal asymptotes of f. If there are no horizontal asymptotes, enter 'NONE'. Horizontal asymptotes y = (I) List all vertical asymptotes of f. If there are no vertical asymptotes, enter 'NONE'. vertical asymptotes r = (J) Use all of the preceding information to sketch a graph of f. When you're finished, enter a "1" in the box below.
