At least one of the answers above is NOT correct. (1 point) Consider the function f(x) A = 2 and B = 7 f" (A) 9 f" (B) -9 Thus f(x) has a local MIN and a local MAX = = : −2x³ +27x² − 84x + 10. This function has two critical numbers A< B: at B (type in MAX or MIN). Note: You can earn partial credit on this problem.

2. Find the critical values of f. -1,4 Use Key Idea 4 (pp.152-3 in APEX Calculus) by applying the principles to the given function. 1. Determine the domain of f. (as an interval) (-inf,inf) 3. Find the possible points of inflection of f (x-values only). 3/2 (Separate multiple answers by commas.) 4. Find the vertical asymptotes. x = DNE (Separate multiple answers by commas.) 5. Find the horizontal aymptotes. y = DNE f(x) = ) = −x³ +4.5x² + 12x + 5.5 (-1,-1),(-1.5,123),(4,61.5) (Separate multiple answers by commas.) 6. Use a number line analysis to complete the following. f is increasing on: (-1,4) f is decreasing on: f is concave up on: (-inf,3/2) f is concave down on: (3/2,inf) (-inf,-1)U(4,inf) (Separate multiple answers by commas.) (as an interval) (as an interval) (as an interval) (as an interval) 7. Evaluate f at each critical point and possible point of inflection. List all such points below. Each point should be entered as an ordered pair (that is, in the form (x, y)). (Separate multiple answers by commas.)
