| Branches of a Hyperbola | Two symmetrical parts of a hyperbola. |
| Complex Fraction | A fracon that contains a fraction in its numerator or denominator. |
| Constant of Variation | The nonzero constant (usually denoted by a k) in a direct, inverse, or joint variation equation. |
| Cross Multiplying | A method of solving a simple rational equation for which each side of the equation is a single rational expression. |
| Direct Variation | Two variables x and y show this provided y = kx where k is a nonzero constant. |
| Hyperbola | The graphs of rational function of the form y = a/(x – h) + k |
| Inverse Variation | Two variables x and y show this provided y = k/x where k is a nonzero constant. |
| Joint Variation | A relationship that occurs when a quantity varies directly as the product of two or more other quantities. |
| Rational Function | A function of the form f(x) = p(x)/q(x) where p(x) and q(x) are polynomials and q(x) does not equal 0. |
| Simplified Form of a Rational Expression | A rational expression in which the numerator and denominator have no common factors. |
