Consider the function f (x) = 2-1 (a) Find the domain of f (a). Note: Use the letter U for union. To enter oo, type infinity. Domain: (b) Give the horizontal and vertical asymptotes of f (x ), 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: vertical asymptote:[o] Give the intervals of increase and decrease of 3"{33}. Note: Use the letter U for union. To enter 00, type infinity. If the function is never increasing or decreasing, enter Nil-Kin the associated response area. increasing: a : decreasing: E {d} Give the local maximum and minimum values of 3"{33}. Enter your answers in increasing order of the m-value. If there are less than two local extrema, enter NA in the remaining response areas and the corresponding drop-down menu. Include a multiplication sign between symbols. For example, a - :ir. ED ED Ell Ell (e) Give the intervals of concavity of f (x). Note: Use the letter U for union. To enter oo, type infinity. If the function is never concave upward or concave downward, enter NA in the associated response area. concave upward: concave downward: (f) Give the inflection points of f (x). Enter your answers in increasing order of the @-coordinate. If there are less than two points of inflection, enter NA in the remaining response areas. Include a multiplication sign between symbols. For example, a
