Let f (2c ) 20 2 + 5 202 - 1 Find the indicated one-sided limits of f. NOTE: Remember that you use INF for co and -INF for -co. You should also sketch a graph of y = f(x), including vertical and horizontal asymptotes. lim f(x) = INF x->-1 lim f(x) = -INF x--1+ lim f(x) = -INF x-1- lim f(x) = INF x-1+ lim f(x) = 1 lim f(x) = 1
