What is the Domain?

Back

The set of all possible input values (x-values) for a function.

Front

What does it mean if a function has a Domain of All Real Numbers?

Back

It means that any real number can be used as an input for the function.

CCSS.HSF.IF.A.1

Front

What is a function's Range if it is defined as y = x^2?

Back

The Range is y ≥ 0, since the output of x^2 is always non-negative.

Front

How do you determine the Domain of a function from its graph?

Back

The Domain can be found by identifying the x-values for which the graph exists.
