# Radical equations and functions

Contents

In this topic you will learn how to solve radical equations (which are equations with radical expressions in them) while avoiding extraneous solutions. You will also learn how to graph radical functions.

4 exercises available

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

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

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.).
