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

Identify the domain values from the relation: {(2, 3), (4, 5), (6, 7)}

Back

{2, 4, 6}

Front

Identify the range in the following relation: {(1, 2), (3, 4), (5, 6)}

Back

{2, 4, 6}

Front

Front

Is the following mapping a function? {(2, 3), (3, 4), (2, 5)}

Back

Not a Function

Front

Is this a function? {(1, 2), (2, 3), (3, 4)}

Back

Yes, it is a function.

Front

What does it mean for a relation to be not a function?

Back

A relation is not a function if at least one input is associated with more than one output.

Front
