Front

What does it mean if a relation has a domain of -3 < x ≤ 3?

Back

The x-values can be any number greater than -3 and up to and including 3.

Front

What is an example of a relation with a domain of {1, 2, 3}?

Back

A possible relation could be {(1,4), (2,5), (3,6)}.

Front

If a function has a range of {0, 1, 2}, what does this indicate?

Back
