| Question | Answer |
|---|---|
| a grid formed by the intersection of two perpendicular number lines (the x-axis and y-axis) intersecting at a zero point called the origin | coordinate plane |
| a set of ordered pairs, which can be represented in multiple formats including lists, tables, coordinate graphs, or diagrams | relation |
| a visual diagram that illustrates how each specific input element is paired or linked with an output element using directional arrows | mapping |
| the complete set of all first coordinates (x-values) from the ordered pairs in a relation | domain |
| the complete set of all second coordinates (y-values) from the ordered pairs in a relation | range |
| the variable in a relation that represents the input quantity and is completely unaffected by other factors | independent variable |
| the variable in a relation that represents the output quantity and changes in response to the input parameter | dependent variable |
| a relation in which an element of the domain is paired with one element of range | function |
| has a graph with isolated points not connected by an unbroken line | discrete function |
| can be graphed with on smooth continuous line or curve | continuous function |
| if you drop a vertical line on a function it will only pass through once | vertical line test |
| an equation written in the form of a function f of x: f(x) | function notation |
| a function whose rate of change is not constant | nonlinear function |
| what will always be your output? | y |
| what will always be your input? | x |
| how much can an input put out? | no more than one output |
| (true or false) when identifying functions, the main values cannot repeat | true |
| (True or false) in a function x cannot repeat and every input has to have exactly one output | true |
| where a line crosses an axis | intercept |
| where a line crosses the y-axis | y-intercept |
| the graph is above the x-axis | positive |
| the graph goes left to right | increasing |
| a high or low function value | extrema |
| a near by low point | relative minimum |
| where a line crosses the x-axis | x-intercept |
| half of the graph is a mirror image of the other | line symmetry |
| the graph is below the x-axis | negative |
| the graph goes right to left | decreasing |
| the graph goes left to right | increasing |
| a near by high point | relative maximum |
