# How do i graph limits?

Oct 21, 2014

If your function approaches infinity or negative infinity as x approaches your limit you can represent the limit with a line or dashed line:

$f \left(x\right) = \frac{1}{x}$

$\lim x \to 0 + = \infty$
$\lim x \to 0 - = - \infty$

If your function does not trail off into infinity or negative infinite as x approaches your function you can represent the limit with an empty circle:

$f \left(x\right) = \frac{x - 1}{x - 1}$

$\lim x \to 1 =$undefined
