Hi, I'm having trouble with the problem. Can you please help me?

Consider the function f (x) = 1 +2 (a) Find the domain of f (). 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 (x), if any. Enter the equations for the asymptotes. If there is no horizontal or vertical asymptote, enter associated response area. horizontal asymptote: y=1 vertical X=-2 asymptote: (c) Give the intervals of increase and decrease of f (). 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. increasing: (-infinity,-2) U (-2,infinity) decreasing: NA
