15. Consider the function of two variables f(x,y) = 3r5 + 5xy +1649 +e. The variables are restricted to a domain on which the function is defined. (a) Find f (x,y) (b) Find f-(1,2). Give an exact answer, not a rounded decimal, if necessary (c) Find f(x,y) (d) Find f,(1,2) (e) Find all of the second derivatives of f(x,y) 16. Calculate all four second-order partial derivatives for f(x,y) = 13r +6x*y"
