Quadrants | The four parts to a coordinate grid. |
Origin | The point (0,0) on a coordinate grid. |
Relation | A set of ordered pairs. |
Function | A set of ordered pairs where the x's do not repeat. |
Domain | The x values to a set of ordered pairs. |
X-axis | The horizontal axis on a coordinate grid. |

Dependent Variable | The y value of the function. Also called the range. |
The symbol f(x) | Means y. |
Evaluate | To solve |
Commutative Property | The order of the numbers change |
