II. Setting a Window - Finding One That Works

B. Examples

3. Radical Function Examples

i) Example 1: Graph the function . You should note that the domain is , and 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 ZDECM. This is a good window. ZSTD also gives a view of the graph that can be used but is not as good as ZDECM.

Enter the function.
