Use limits involving to to describe the asymptotic behavior of the function from its graph. (If the limit is infinite, enter 'o' or '-', as appropriate. If the limit does not otherwise exist, enter DNE.) x f(x) = (x+4)2 y 15 -20 lim f(x) = 9118 lim X-4 lim x4+ f(x) = f(x) = lim f(x) = 4118 lim f(x) = 818 10 5 X -10 10 20 4 20
