Chapter 1.2, Problem 1QCE

In each part, find the limit by inspection.

(a) $\underset{x\to 8}{\lim }7=\text{\_\_\_\_\_\_}$

(b) $\underset{y\to 3^{+}}{\lim }12y=\text{\_\_\_\_\_\_}$

(c) $\underset{x\to 0^{-}}{\lim }\frac{x}{\left|x\right|}=\text{\_\_\_\_\_\_}$

(d) $\underset{w\to 5}{\lim }\frac{w}{\left|w\right|}=\text{\_\_\_\_\_\_}$

(e) $\underset{z\to 1^{-}}{\lim }\frac{1}{1-z}=\text{\_\_\_\_\_\_}$
