(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. -10x lim 2-900 15 + 2x 2x - 14 lim 14-00 3 + 3x -13 - 8x - 4 lim I-+00 11 - 11x2 Vx2 + 14x lim 2 - 15x Vx2 + 14x lim 157
