Term | Definition |
Domain | The x values taken by a relation. (or, how far left and right a relation goes.) |
Range | The y values taken by a relation. (or, how far down and up a relation goes.) |
Interpolate | To use a graph to find the x or y value of a point between known (given) points. |
Extrapolate | To use a graph to find the x or y value of a point beyond known (given) points. |
Function | A special type of relation that has only one y value for each x. It passes the vertical line test. |
Linear Function | A straight line that is sloped. |
Constant Function | A flat (horizontal) line. There is no x variable. For example: y=5 |
Independent variable | The variable plotted on the x axis. Time is usually independent. |
Discrete | A relation in which given values cannot be joined - it's a series of separate points. |
Continuous | A type of relation in which the given points are only a few of the valid points. The relation includes infinitely many points in between those. |
Direct Variation | A linear function that passes through the origin |
Partial Variation | A linear function that does not pass through the origin. |
Constant of Variation | In direct variation, the amount the line rises divided by amount it goes to the right between two points. Also called a constant of proportionality. |
Fixed value | In a partial variation, the value of the dependent variable (y) when the independent variable is 0 (in other words the y intercept). |
y intercept | In a relation that is graphed, the y value when the x is zero. In other words, the height the graph crosses the y axis at. |
x intercept | In a relation that is graphed, the x value when the y is zero. In other words, the place(s) the relation touches the x axis. |
