Why did the applet used in Try This 3 use the form 
and not the form 
Look at an example of two radical functions to help understand how the a and b parameters can both be used to describe stretches of radical functions.
Try This 4
You will look at the graphs of the function 
and 
to see how these two functions are related.
- Describe how to transform the graph of
to produce the graph of the function 
- Describe how to transform the graph of
to produce the graph of the function 
- Graph each of the two functions
and 
Use a graphing calculator or graphing program; or graph them by hand. - Are the two functions
and 
equivalent? Explain your reasoning.
