Classifying Direct and Inverse Variation • When two variables x and y show direct variation when y = ax for some nonzero constant a. Another type of variation is called inverse variation.
You Try Tell whether x and y show direct variation, inverse variation, or neither.
Writing Inverse Variation Equations The variables x and y vary inversely, and y = 4 when x = 3. Write an equation that relates x and y. Then find y when x = −2.
Bellwork • The variables x and y vary inversely. Use the given values to write an equation relating x and y. Then find y when x = 3.

What is asymptote? A line that continually approaches a given curve but does not meet it at any finite distance. When a Domain is not continous?
Slant Asymptotes • Finding Slant Asymptotes of Rational Functions. • A slant (oblique) asymptote occurs when the polynomial in the numerator is a higher degree than the polynomial in the denominator. To find the slant asymptote you must divide the numerator by the denominator using either long division or synthetic division.
