Evaluate fx, fy, fz at the given point a) f (x, y z) = x³yz² at the point (1, 2, 3) b) f (x, y, z) = x² - 2xy + 3yxz² at the point (3, 1, -2)

Step-by-step explanation:

a) The partial derivatives of f(x, y, z) = x³yz² are ...

At the given point, these are ...

__

b) The partial derivatives of f(x, y, z) = x² -2xy +3xyz² are ...

At the given point, these are ...

i believe that the answer is

b. y-1=-2(x-4)

hope this !

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
