Question

Suppose that z is a linear function of x and y with slope -3 in the x direction and slope 1 in the y direction.

(a) A change of 0.4 in x and -0.5 in y produces what change in z?
change in z =

Answer 1

Please help me with this

Answer 2

ok. you know that the equation is z=-3x+y. Now take partial derivative of z with respect to x. so you get dz=-3dx. Also take partial derivative of z with respect to y. So you get dz=dy. Now dx=0.4 and dy=-0.5. So find dz
