I am currently preparing a class on finding the extremum of multivariable functions and would appreciate some assistance. I intend to use Geogebra to aid in my teaching, and I am looking for a function that exhibits multiple "bumps" similar to the image I have provided. The ideal function would allow me to manipulate the view and animate it during the class.
If anyone could help me generate such a function or provide guidance on how to create one, I would be extremely grateful. Your expertise and support would greatly enhance my teaching materials.
Thank you in advance for your valuable assistance.
