2.3 Exercises 1. Given that lim f (x) = -3 (c) lim Vh(x) (d) lim lim g(x) = 0 lim h(x) = 8 x - a x-a f (x) x - x - find the limits that exist. If the limit does not exist, explain f (x) (e) lim (f) lim g(x) why. x-a h(x) x-a f ( x) (a) lim [f(x) + h(x)] f (x) 2f (x) (b) lim [f (x) 12 (g) lim (h) lim xza g(x) x-a h(xx) - f(x)
