| Domain of a Function | The set of values of the independent variable(s) (the input) for which a function or relation is defined. |
| Horizontal Asymptote | A flat or level line that the graph of a relation approaches more and more closely the further the graph is followed. |
| Hyperbola | graph of a rational function. |
| Range of a Function | The set of y-values of a function or relation. |
| Rational Function | A function that can be written as a polynomial divided by a polynomial. |
| Simplified Form of a Rational Function | A rational function in which the numerator and denominator have no common factors. |
| Slant Asymptote | a diagonal line that the graph of a relation approaches more and more closely the further the graph is followed. |
| Vertical Asymptote | A straight up or down line that the graph of a relation approaches more and more closely the further the graph is followed |
| x-intercept | A point at which a graph intersects the x-axis. Also called roots or zeros of a function. |
| y-intercept | A point at which a graph intersects the y-axis. |
