| A | B |
|---|
| x-axis | the horizontal number line |
| y-axis | the vertical number line |
| origin | the point at which the axes of the coordinate plane intersect |
| Quadrant | the four regions into which the two perpendicular lines separate the plane |
| relation | a set of ordered pairs |
| domain | the set of all first coordinates from the ordered pairs in a relation |
| mapping | shows how each member of the domain is paired with each member of the range |
| ordered pair | the coordinates of the point |
| coordinate system | composed of two perpendicular lines intersecting at their zero points creating a coordinate plane upon which ordered pairs may be graphed |
| vertical line test | method to determine if the graph of a relation is a function |
| function | a special type of relation in which each element of the domain is paired with exactly one element of the range |
| range | the set of all second coordinates from the ordered pairs in a relation |
| discrete function | the domain of the function is a set of individual points |
| continuous function | the domain of the function has an infinite number of elements and can be graphed with a line or smooth curve |
