Chapter 2.3, Problem 2E

Tire graphs of f and g are given. Use them to evaluate each limit, if it exists. If the limit does not exist, explain why.

(a) $\underset{x\to 2}{\lim }[f(x)+g(x)]$

(b) $\underset{x\to 0}{\lim }[f(x)-g(x)]$

(c) $\underset{x\to -1}{\lim }[f(x)g(x)]$

(d) $\underset{x\to 3}{\lim }\frac{f(x)}{g(x)}$

(e) $\underset{x\to 2}{\lim }[x^{2}f(x)]$

(f) $f(-1)+\underset{x\to -1}{\lim }g(x)$
