Answer 1

We are asked to determine what happens to the values of $f(x)$ as $x$ approaches $2$ using values of $x$  less than $2$ AND using values of $x$ greater than $2$ . 

Observe from the graph that as $x$ approaches $2$ from the left or the right, the values of $f(x)$ increase without bound.

Therefore, we know the following. 

$\text{lim} \ f(x) = +\infty}$
