Terms | Definitions |
|---|---|
 Function | A function is a relationship between two quantities in which one quantity is associated with a unique value of the other quantity. |
| Direct Variation | In a direct variation, the ratio of the value of the dependent variable to the value of the independent variable is constant. |
| Proportional | A proportional relationship is a relationship between two changing quantities in which the ratio between the two quantities remains constant. |
| Constant of Proportionality | The constant of proportionality is the name given to the ratio of two proportional quantities. If x and y represent two proportional quantities, then y/x=k where k is the constant of proportionality. This can also be written as y = x*k |
| Constant of Variation | The constant of variation is the nonzero ratio between two variables in a direct variation or the nonzero product of two variables in an inverse variation. |
| Inverse Variation | In inverse variation, the product of the value of the independent variable and the value of the dependent variable is constant. This is written as x*y, or y=k/x. |
| Absolute Variation | The absolute value of a number is the distance between 0 and the number on a number line. As shown on the number line in the image, the absolute value of 3 is 3. This is written | 3 | = 3. The absolute value of -3 is also 3; | -3 | = 3. |
| Horizontal Asymptote | The horizontal line y = c is a horizontal asymptote of a function if the values of the function approach the constant c as the positive values of x grow larger or the negative values of x grow smaller. |
