8 CCSSM FUNCTIONS
8th MATH FUNCTIONS COMMON CORE - COMPLETE
| Term | Definition |
|---|---|
| function | a relation in which every domain value is paired with exactly one range value; the out put depends on the input |
| x-value | The horizontal value in a pair of coordinates: how far along the point is. This is always written first part of a pair of coordinates. |
| vertical line test | a test to determine whether a relation is a function. If any vertical line passes through no more than one point of the graph of a relation, then the relation is a function. |
| input | a value that is substituted for the independent variable in a relation or function (the number on which a function operates) |
| output | the result of substituting a value for a variable in a function |
| rate of change | how steep functions go up or down from the initial value a measure of how quickly something changes. |
| linear function | an equation whose graphs is a non vertical line; a function that can be written as y = mx + b where x = the independent variable, and m and b are real numbers. |
| non-linear function | creates a graph that is not a straight line |
| linear relationship | when two variables or quantities are proportionate to one another. As one variable changes, there is a constant rate of change in another variable. In a graphic representation, this is a straight line that passes through data points based on the slope an |
| slope | a measure of the steepness of a line; the ratio of the rise to the run as you move from one point to another along a line |
| initial value | where functions start |
| y-intercept | the y coordinate(s) of the point(s) where a graph intercepts the y-axis |
| y-value | The vertical value in a pair of coordinates, always written second in an ordered pair of coordinates |
| x-intercept | the x coordinate(s) of the point(s) where a graph intercepts the x-axis |
