| asymptote | a line that a graph approaches as the value of a variable becomes extremely large or small |
| closure | a set of numbers has this under a given operation if the result of the operation on any two numbers in the set is also in the set. |
| cube-root function | a root function with an index of 3 |
| end behavior | the trends in the y-values of a function as the x-values approach positive and negative infinity |
| excluded values | values of x for which a function or expression is not defined |
