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. -4x lim 14 + 2x 7x - 9 lim x--0o x3 + 6x -3 2 - 15x - 10 lim 15 - 15x2\fEvaluate , 3 6:34 11m . git>00 5 | 73:4 If the limit is 00, enter 'INF', and if the limit is 00, then enter 'INF'. Limit = f, Evaluate the following limits. If needed, enter 'INF' for co and '-INF for -co.
