An Acceptable Wave Function

You probably found making smooth connections at both boundaries difficult. Get one right, and the other one is messed up. Sometimes it will work; more often it does not. What would you need to change to create an acceptable wave function?
 
To see that we can draw wave functions for this situation, set up the following parameters.
 
 
Potential Minimum = -4.32 eV Potential Width = 0.71 nm Total Energy = -1.32 eV
 
Use Wave Function Sketcher, then sketch or print your wave function.
