Stiep $1$

Recall that if a function $f(x)$ becomes arbaterfy close to a single number i as $x$ appreaches $c$ from ether side, then the linet of $f.$

$\underset{xc}{lim}f(x)=1$

Many times the limit of $f(x)$ as $x$ appreaches $c$ is simply $f(c).$ In those cases we can state the following.

$\underset{xe}{lim}f(x)=f(c)$

In these cases the limit can be evaluated by direct substitution. In other words, it can be found by evaluating the forction for at

We wish to find the limit $\underset{x8}{lim}(-x^{2}x-8)$ vio direct substitution. Is other words, we need to evaluate f $$ for she
