Set the argument of the logarithm equal to zero.

$x = 0$

The vertical asymptote occurs at $x = 0$ .

Vertical Asymptote: $x = 0$

Find the point at $x = 1$ .

Replace the variable $x$ with $1$ in the expression.

$f (1) = \ln (u)$

The final answer is $\ln (u)$ .

$\ln (u)$

Convert $\ln (u)$ to decimal.

$y = \ln (u)$

The log function can be graphed using the vertical asymptote at $x = 0$ and the points $(1, \ln (u)), (2, \ln (u)), (3, \ln (u))$ .

Vertical Asymptote: $x = 0$

$\begin{array}{c} x & y \\ 1 & \ln (u) \\ 2 & \ln (u) \\ 3 & \ln (u) \end{array}$
