use MatLab to solve. Can you show me the code and graph for the question? Thank you!

(Section 144 # 45. 53) Use Matlab to graph the functions using different donans and viewpoints. Get a printout of one that, in your opinion, gives a good view. Plot also some contour curves of the same function and compare with the graph. A possible choice of a domain would be r e [-22,v-22 (a) fx.y Note: commands meshgrid, mesh, surf contour may be useful in plotting surfaces and contour curves
