Extraneous_solutions_of_radical_equations

Learn about the conditions for obtaining extraneous solutions while solving radical equations.

Square_root_equations

Learn how to solve equations with square-root expressions in them. For example, solve √(2x-5)=√(7-3x).

Graphs_of_radical_functions

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

Cube_root_equations

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

Domain_of_radical_functions

Learn how the domain of radical functions is determined.
