| Control variable | The independent variable, usually x |
| Dependent variable | Depends on control variable, usually y |
| Growth graph | A graph which is increasing throughout |
| Decay graph | A graph which is decreasing throughout |
| Constant graph | A graph which is linear and horizontal |
| Domain | All the values of the control variable (x) |
