What is a mapping diagram?

Back

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

Front

What is the vertical line test?

Back

A method to determine if a graph represents a function; if a vertical line crosses the graph more than once, it is not a function.

What are inputs in a function?

Back

The values that are fed into a function, often represented as x-values.

Front

What are outputs in a function?

Back

The results produced by a function, often represented as y-values.
