Please someone help, I got it wrong and here is my work.

solution. - Given that Play ) 2 - 2x7 - 342 ( a ) First get the descivation of the function with respect to xandy Fx ? [-16x ]e ( - 2x4 - 3 32 ) Py = [- ay Je - 2x " - 342) To find the cortical Points , we solve fx 2 0 , fy zo and get 2 20 420 then ( x y ) 2 cool . . i the critical point-is : cool (b ) f ( x, y ) 2 2x 2 3 4 2 First get the derivative of the function with respect to xandy fy . [- qy ] ( 2* - 342 ) To find the critical points , we solve faro Pyroand get x20 y id than( x y ) 2 (0.0 ) - (C ) F ( x . JJ 2 2 x 2+3 4 2+2 First get the desilvate of the function with suspect to xand y Pezux, Pyzay To find the critical point we solve fxxzo fyzo and get 10 1 . .At Point ( o.. ) we have D 2 AC - 12 - 36 -0 -36 D>o Ajo (o. . ) is a point of local minima ( D ) f ( x 1 ) = 2x + 3 4 + 2 Fistget the dexivative of the function with respect to xand y . To find the critical point _ be save we are not able to find the value of x_ andy there one no critical points . To minima, No maxima. Answer .Safari File Edit View History Bookmarks Window . @ E] v
