B. Examples

3. Radical Function Examples

i) Example 1: Graph the function . You should note that the domain is , so your window should reflect this.

Enter the function.
Set a window.
Graph.

ii) Example 2: Graph the function . You can enter the function as a radical or with an exponent. In this example, the function is entered using an exponent. The domain is all real numbers, so the first window choice is ZOOM4. This is a good window. ZOOM6 also gives a view of the graph that can be used but is not as good as ZOOM4.

Enter the function.
