Learn how to solve equations with cube-root expressions in them. For example, solve ∛(2-6x)=x+3.

Learn how the domain of radical functions is determined.

Learn how the graphs of radical functions look, and how we can reason about them using function transformations (i.e. shifts, stretches, etc.).
