Identifying Functions

Front

What is the 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 does it mean for a graph to be a function?

Back

A graph is a function if every input (x-value) has exactly one output (y-value).

Front

What is a non-function?

Back

A relation where at least one input has more than one output.

Front

What is a linear function?

Back

A function that graphs to a straight line, represented by the equation y = mx + b.

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

How can you tell if a graph is not a function?

Back

If a vertical line drawn through the graph intersects it at more than one point.

Front

What is a mapping in mathematics?

Back

A way to show how each input is paired with an output.

Front

What is a function table?

Back

A table that shows pairs of inputs and outputs for a function.

Front

What is the difference between a function and a non-function?

Back

A function has one output for each input, while a non-function has at least one input with multiple outputs.

Front

What does it mean for a function to be defined?

Back

It means that for every input, there is a corresponding output.
