|---|---|---|---|---|---|
| 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.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
