What is the definition of the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

In set builder notation, how is the range of a function represented?

Back

The range is represented as {y | condition on y}, indicating the values y can take.

If a function has a range of {y | -2 ≤ y ≤ 2}, what does this mean?

Back

This means that the output values (y) of the function can be any number between -2 and 2, inclusive.
