From the table it follows that as $x$ gets closer to $1$ from the left side
of $1,$ $f(x)$ gets closer to $3.$ Similarly, when $x$ gets closer to $1$
from the right side of $1,$ then $f(x)$ gets closer to $3.$ In cases such as
these, we say that limit of $f(x)$ as $x$ approaches to $1$ is $3,$ and we
expresses this by writing
\begin{equation*}
a+b+c+d\margintext{Rewrite the expression using
fractional and negative indices.}
\end{equation*}
