Functions

Front

What are all of the y values or outputs called?

Back

Range

Front

What are all of the x values or inputs called?

Back

Domain

Front

Is this graph a function or not a function? (Provide a graph showing a vertical line that intersects the graph at one point)

Back

Function

Front

Is this mapping a function or not a function? (Provide a mapping diagram showing one input mapping to multiple outputs)

Back

Not a Function

Front

Give the domain and range. Tell if it is a function. D: {-4, -2, 0, 2}, R: {-2, -2, 1, 1}

Back

D: {-4, -2, 0, 2}, R: {-2, 1}, Function

Front

What is a function?

Back

A relation where each input has exactly one output.

Front

What is the definition of domain?

Back

The set of all possible input values (x values) for a function.

Front

What is the definition of range?

Back

The set of all possible output values (y values) for a function.

Front

What is a vertical line test?

Back

A method to determine if a graph represents a function; if a vertical line intersects the graph at more than one point, it is not a function.

Front

What is a mapping diagram?

Back

A visual representation of a function showing how each input is paired with an output.
