ROOT FUNCTIONS Graphing And Analysis (Page 3 of 5)

As a second example, we will graph the root function f(x) = 5thRoot(x+3). Enter this function as Y1 (clear the previous function). You will need the general root command found in the MATH MATH submenu. The index 5 is entered first, then the root command. Once entered, try a standard window.

 Y= key. CLEAR key.

 5 MATH key. 5: menu selection. Left parenthesis key. X,T,theta,n key. Plus key. 3 Right parenthesis key.

 ZOOM key. 6: menu selection.

The standard window is a comprehensive graph, but we can improve the perspective by narrowing the range in the y-direction.
