Understanding Functions and Relations

A relation pairs each input with multiple outputs.

A function pairs each input with exactly one output.

A function can have multiple outputs for a single input.

A relation can have only one output for each input.

Each input is paired with a unique output.

An input is paired with multiple outputs.

All outputs are the same.

There are no inputs.

If any output values are repeated.

If all output values are different.

If any input values are repeated.

If all input values are different.

Yes, all range values must be unique.

No, range values can repeat.

Yes, but only if the domain values are unique.

No, as long as each domain value maps to one range value.

The list is in set notation.

All range values are the same.

A domain value is paired with different range values.

All domain values are unique.

It always indicates a function.

It indicates a function if paired with the same range value.

It indicates a relation but not a function.

It has no significance.

To determine if a graph is a relation.

To check if a graph represents a function.

To identify the range of a function.

To find the slope of a graph.

The graph represents a function.

The graph does not represent a function.

The graph is a quadratic function.

The graph is a linear function.

Diagonal axis

None of the above

Horizontal axis

Vertical axis

The graph is a relation.

The graph is a function.

The graph is not a function.

The graph is undefined.
