## How do you find a horizontal asymptote?

**To find horizontal asymptotes:**

- If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0).
- If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

## How do you find the vertical and horizontal asymptotes of a graph?

The graph will have a vertical asymptote at x=a if the denominator is zero at x=a and the numerator isn’t zero at x=a . If n<m then the x -axis is the horizontal asymptote. Ifn=m then the line y=ab y = a b is the horizontal asymptote. If n>m there will be no horizontal asymptotes.
