| 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 |
| range | the y values to a set of ordered pairs |
| discrete | individual points that would be connected when graphed because not all rational values define the domain |
| continuous | an infinite number of points that are connected when graphed because all real values can be defined in the domain |
