$f (x) = \log_{2} (x - 1)$

Step 1

Set the argument of the logarithm equal to zero.

$x - 1 = 0$

Step 2

Add $1$ to both sides of the equation.

$x = 1$

Step 3

The vertical asymptote occurs at $x = 1$ .

Vertical Asymptote: $x = 1$

Step 4

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
