Chapter 3.1, Problem 1E

In Exercises 1–4, use the given table of values to estimate, for the given value of a, each of the following if they exist:

(a) $\underset{x\to a^{-}}{\lim }f\left(x\right)$

(b) $\underset{x\to a^{+}}{\lim }f\left(x\right)$

(c) $\underset{x\to a}{\lim }f\left(x\right)$

(d) $f\left(a\right)$ if it is defined

[HINT: See Example 1-3]

$a=2;$ table of values:

$x$	1.9	1.99	1.999	1.9999	2	2.0001	2.001	2.01	2.1
$f\left(x\right)$	–5.975	–5.9975	–5.99975	–5.999975	–4	440,000	44,000	4,400	440
