$f (x) = \log_{2} (x + 2)$

Step 1

Set the argument of the logarithm equal to zero.

$x + 2 = 0$

Step 2

Subtract $2$ from both sides of the equation.

$x = - 2$

Step 3

The vertical asymptote occurs at $x = - 2$ .

Vertical Asymptote: $x = - 2$

Step 4

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