WebEasy Solution Verified by Toppr Correct option is B) f(x+y)⋅f(x−y) =( 22 x+y+2 −(x+y))( 22 x−y+2 −(x−y)) = 41(2 2x+2 2y+2 −2x+2 −2y) = 21[21(2 2x+2 −2x)+ 21( 2y+2 −2y)] = … Webf(x,y) = 3x2y+y3 −3x2− 3y2 +2. Solution The first and second partial derivatives of f are: f x(x,y) = 6xy−6x, f y(x,y) = 3x2+3y2−6y, f xx(x,y) = 6y−6, f xy(x,y) = 6x, f yy(x,y) = 6y−6. First find the critical points: f x(x,y) = 0 and f y(x,y) = 0 =⇒ (x,y) = (0,0), (0,2), (1,1), (−1,1). To classify these points we need to ...
