Why does the graph of \sqrt[3]{x} have negative y-values instead of imaginary like \sqrt{x}?

The cube root of negative numbers are imaginary.

The cube root of negative numbers are negative.

The cube root of positive numbers are negative.

Notice how there are arrows on both ends of the curve.
What do you think the range is?

The domain and range will ALWAYS be the same for every cube root function, because the graph will always go on forever in both directions.

The same transformation rules apply for cube root functions:
