Front

Define a function in mathematical terms.

Back

A function is a relation where each input (x value) has exactly one output (y value).

Front

What is the difference between a relation and a function?

Back

A relation is a set of ordered pairs, while a function is a specific type of relation where each input is associated with exactly one output.

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Front

How can you determine if a relation is a function using the vertical line test?

Back

If a vertical line intersects the graph of the relation at more than one point, it is not a function.
