Consider the function f (ac) = x-2 (a) Find the domain of f (a). Note: Use the letter U for union. To enter oo, type infinity. Domain: (-infinity, -2) U (-2, 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: X vertical asymptote: -2 X
