### Course: Algebra 2 > Unit 9

Lesson 6: Graphs of square and cube root functions# Radical functions & their graphs

Practice some problems before going into the exercise.

## Introduction

#### In this article, we will practice a couple of problems where we should match the appropriate graph to a given radical function.

### Practice question 1: Square-root function

The graph of $y=\sqrt{x}$ is shown below.

### Practice question 2: Cube-root function

The graph of $y=\sqrt[3]{\phantom{A}x}$ is shown below.
