Consider the function f (ac) = 20 -3 2c + 2 (a) Find the domain of f (ac). Note: Use the letter U for union. To enter oo, type infinity. Domai (-infinity,-3)U(-3,infinity) (b) Give the horizontal and vertical asymptotes of f (a), if any. Enter the equations for the asymptotes. If there is no horizontal or vertical asymptote, enter NA in the associated response area. horizontal asymptote: Y=-3 P vertical asymptote: X=2 (c) Give the intervals of increase and decrease of f (ac). Note: Use the letter U for union. To enter oo, type infinity. If the function is never increasing or decreasing, enter NA in the associated response area. increasinginity,-3) U(-2,infinity) decreas
