1.) Find the local maximum and minimum values and saddle point(s) (x,y,f) of the function. If you have three-dimensional graphing software, graph the function with a domain and viewpoint that reveal all the important aspects of the function. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.)
f (x, y) = xy − 5x − 5y − x2 − y2
2.)Find the local maximum and minimum values and saddle point(s)(x,y,f) of the function. If you have three-dimensional graphing software, graph the function with a domain and viewpoint that reveal all the important aspects of the function. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.)
f(x, y) = x3 + y3 − 3x2 − 9y2 − 9x
3.)Find the local maximum and minimum values and saddle point(s)(x,y,f) of the function. If you have three-dimensional graphing software, graph the function with a domain and viewpoint that reveal all the important aspects of the function. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.)
f(x, y) = 5y cos(x), 0 ≤ x ≤ 2π
Graph is given at end 1 st image fir part 1 and 2 nd for part 2
Note only 2 questions are allowed to answer ar atime I have given one extra hope u can do the rest
