# What are the asymptotes of #y=2/(x+1)-4# and how do you graph the function?

##### 1 Answer

This type of question is asking you think about how numbers behave when grouped together in an equation.

#### Explanation:

It is not allowed (undefined) when a denominator takes on the value of 0. So as

It is always worth investigation when the denominators approach 0 as this is usually an asymptote.

Suppose

In the same way as x tends to the positive side of -1 then

As x tends to positive

You have the same as x tends to negative

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You have a horizontal asymptote at

You have a vertical asymptote at
