Find the 2 critical points of the given function and then determine whether it is a local maximum, local minimum, or saddle poin
grandymaker [24]

Answer:

Step-by-step explanation:

Given is a function f in two variables as

f(x, y) = (x − y)(xy − 9)

To find critical points of the given function and also to find max, min or saddle point.

Find the partial derivatives

f(x,y) = x^2y-xy^2-9x+9y

f_x=2xy-y^2-9\\f_y =x^2-2xy+9\\f_{xy}  =2x-2y = f_{yx}

f_{xx}=2y\\ f_{yy}=-2x

Equate first derivatives to 0

Adding fx and fy we get

x^2-y^2 =0\\

x=±y

Only real roots are (x,y) =(3,3) and (-3,-3)

D(3,3)=f_{xx}(3,3) f_{yy}(3,3)-f_{xy}^2(3,3) \\=-36-0

(3,3) is a saddle point

D(-3,-3) = -36

(-3,-3) is also a saddle point.

Hello, a Maths question if anyone knows what to do Solve: 6(x+4)=30
eduard

Answer:

x = 1

Step-by-step explanation:

6(x+4)=30    (divide both sides by 6)

(x+4) = 30/6

x+4 = 5   (subtract 4 from both sides)

x = 5 - 4

x = 1
