Question

How do i graph limits?

Answer 1

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(x)=1/x`

`limx->0+ = oo`
`limx->0- = -oo`

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(x) = (x - 1)/(x-1)`

`limx->1=`undefined
