Question

5–22 find the local maximum and minimum values and saddle point(s) of the function. you are encouraged to use a calculator or computer to graph the function with a domain and viewpoint that reveals all the important aspects of the function.

1. ( f(x, y) = x^2 + xy + y^2 + y )
2. ( f(x, y) = xy - 2x - 2y - x^2 - y^2 )
3. ( f(x, y) = 2x^2 - 8xy + y^4 - 4y^3 )
4. ( f(x, y) = x^3 + y^3 + 3xy )
5. ( f(x, y) = (x - y)(1 - xy) )
6. ( f(x, y) = y(e^x - 1) )
7. ( f(x, y) = ysqrt{x} - y^2 - 2x + 7y )
8. ( f(x, y) = 2 - x^4 + 2x^2 - y^2 )
9. ( f(x, y) = x^3 - 3x + 3xy^2 )
10. ( f(x, y) = x^3 + y^3 - 3x^2 - 3y^2 - 9x )
11. ( f(x, y) = x^4 - 2x^2 + y^3 - 3y )
12. ( f(x, y) = x^2 + y^4 + 2xy )
13. ( f(x, y) = xy - x^2y - xy^2 )
14. ( f(x, y) = (6x - x^2)(4y - y^2) )
15. ( f(x, y) = e^x cos y )

(partial 20: ( (x^2 + y^2)e^{-x} ))
