$f(x) = cot~3x$
When $x = 0$, there is an asymptote. This is the graph for a cotangent function. Compared with a standard cotangent function, the first positive asymptote occurs at $x = \frac{\pi}{3}$ instead of $\pi$. Therefore we need to include the term $3x$ for the angle in the function. The equation for this graph is: $f(x) = cot~3x$
