Question 2. Suppose that the function f has the following graph on (-5,5). 2 fullt (a) Does the limit lim f(a) exist? If it exists, evaluate it; if not, explain why.

In parts (b) to (d), determine the indicated limit of f(f(x)), if it exists. Explain your solution carefully. (b) lim f(f(x)) (c) lim f(f(x)) H--3 (d) lim f(f(x))
