Answer
$f\left( x \right)\to \infty $ as $x\to {{2}^{-}}$ or as $x\to -{{2}^{+}}$.
Work Step by Step
The expression $f\left( x \right)\to \infty $ shows at what value of x the value of the y-axis would tend to infinity.
We see that as x approaches $-2$ from the right, that is as $x\to -{{2}^{+}}$, then $f\left( x \right)\to \infty $.
Further, as x approaches 2 from the left, that is $x\to {{2}^{-}}$, then $f\left( x \right)\to \infty $.
Thus, $f\left( x \right)\to \infty $ , as, $x\to -{{2}^{+}}$ or as $x\to {{2}^{-}}$.
