| Non-Linear Graph | a graph that is not a line |
| Mapping | represents two sets of objects or items |
| Set | a collection of numbers, geometric figures, letters, or other objects that have some characteristic in common |
| Function | maps each input to one and only one output |
| Input | the first coordinate of an ordered pair in a relation |
| Output | the second coordinate of an ordered pair in a relation |
| Domain | the set of all the inputs of a function |
| Range | the set of all the outputs of a function |
| Scatter Plot | a graph of a collection of ordered pairs that allows an exploration of the relationship between the points |

| Absolute Value Function | a function that can be written in the form f(x) = |x| |
| Square or Quadratic Function | a function that can be written in the form f(x) = ax^2 + bx + c, where a, b, and c are any numbers and a does not equal zero |
