(1 point) A function is said to have a horizontal asymptote if either the limit at infinity exists or the limit at negative infinity exists. Show that each of the following functions has a horizontal asymptote by calculating the given limit. lim -4x -1/9 I-too 2 + 2x 5x - 3 lim -2 x-+-co 3 + 9x -7 x2- 4x - 9 lim 0 I-+OO 5 - 922 lim Vez+ 5x 0 r-too 4 - 15x lim Vaz+ 5x 1/15 1 4 00 4 - 15x Note: You can earn partial credit on this problem.
