#### Answer

The equation of the vertical asymptote of the function $f\left( x \right)$ is $\underline{x=1}$.

#### Work Step by Step

The vertical asymptote is a vertical line which the function approaches but does not touch.
It is clear from the graph that the value of the function is tending to $\infty $, therefore, the vertical asymptote is $x=1$.
Therefore, the equation of the vertical asymptote is $x=1$.
