1. Use the graph of the function y = f (x) shown above to either evaluate the expression or determine that it does not exist. If it does not exist, explain why. a. lim f (x) x -0 - b. lim f(x) x-0+ c. lim f(x) x-1- d. lim f(x) *+3+ e. lim f (x) x-2 2. Approximate the value of the limit rounded to six decimal places by evaluating the function at the given numbers. Show all function evaluations rounded to six decimal places. 2x -4 lim - x-2x - 2' x = 2.01, 2.001, 2.0001, 1.9999, 1.999, 1.99
