f (x) = \ln (x + 3)

$f (x) = \ln (x + 3)$

Step 1

Set the argument of the logarithm equal to zero.

x + 3 = 0

$x + 3 = 0$

Step 2

Subtract

3

$3$ from both sides of the equation.

x = - 3

$x = - 3$

Step 3

The vertical asymptote occurs at

x = - 3

$x = - 3$ .

Vertical Asymptote:

x = - 3

$x = - 3$

Step 4

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

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