Chapter 1.1, Problem 4QCE

Use the accompanying graph of $y=f\left(x\right)\left(-\infty <x<3\right)$ to determine the limits.

(a) $\underset{x\to 0}{\lim }f\left(x\right)=\text{\_\_\_\_\_\_\_}$

(b) $\underset{x\to 2^{-}}{\lim }f\left(x\right)=\text{\_\_\_\_\_\_\_}$

(c) $\underset{x\to 2^{+}}{\lim }f\left(x\right)=\text{\_\_\_\_\_\_\_}$

(d) $\underset{x\to 3^{-}}{\lim }f\left(x\right)=\text{\_\_\_\_\_\_\_}$
