Bellwork Find the inverse of the following functions

Inverse Variation Section 7.1

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.

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.

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.
