8.2.2 Radical Functions Key Objectives • Graph radical functions and inequalities. • Transform radical functions by changing parameters. Key Terms • A radical function is a function whose rule contains a variable within a radical. • A square-root function is a radical function whose rule contains a variable under a square-root sign. Example 1 Graphing Radical Functions When using a table to graph square-root functions, choose x -values that make the radicands perfect squares. When using a table to graph cube root functions, choose x -values that make the radicands perfect cubes.
