1. Evaluate the limit algebraically, if it exists. If the limit does not exist, explain why. If the limit is infinity(- or +), state it. x+1 lim x45x-5 2. For the function f(x) whose graph is given, state the value of each quantity, if it exists. If the limit does not exist, state "DNE". 2- 2 a) lim f(x) x+0 b) lim f(x) x+4 4 c) f(2) d) lim f(x) x-2- e) lim f(x) x+2
