Question | Answer |
---|---|
Relation | Any pair of numbers with a connection between them |
Function | A relation where every X value only has one Y value paired with it |
Independent variable | the X value in a relation, will stay the same no matter what the Y value is |
Dependent variable | The Y value in a relation, is dependent on what the X value is |
Output | The Y value/dependent variable in a relation |
Input | The X value/independent variable |
Domain | The set of input values, Independent variables, or X values |
Range | The set off Y values,dependent variables,or Output variables |
Vertical line test | THE test where on a graph you draw vertical lines through the relation to test if it is a function, if the line passes through the relation line twice than it is not a function |
Coordinate plane | The Graph where functions and relations, also data are plotted |
Evaluate | To solve a problem |
Function Notation | The language of math where you list the domain and range of a relation |
Linear | it means that in relation the change of an X value leads to the change of the y value |
Common difference | The difference between numbers in a relation that they share |
