Term | Definition |
---|---|
Function | a relationship that pairs each input with exactly one output |
Domain | a set of all input values of a function |
Range | the set of all output values of a function |
Independent Variable | the variable that represents input values of a function |
Dependent Variable | the variable that represents output values of a function |
Relation | pairs inputs with outputs; A relation that pairs each input with exactly one output is a function |
Vertical Line Test (VLT) | a graph represents a function when no vertical line passes through more than one point on the graph |
Discrete Domain | a set of input values that consists of only CERTAIN numbers in an interval |
Continuous Domain | a set of input values that consists of ALL numbers in an interval |
Linear Function | a function whose graph is a non vertical line; can be written in y=mx+b |
Function Notation | a way to name a function using f(x) instead of y; read as "f of x" |
Absolute Value Function | a function that has a V-shaped graph that opens up or down; most basic one is f(x)=|x| |
Nonlinear Function | a function that does not have a constant rate of change; not a line |
