Question #4169

Determine the relative extrema of the function h = x[sup]2[/sup] + (y - 3)[sup]2[/sup] + (z + 1)[sup]2[/sup]

Expert's answer

relative extrema: dh/dx=2x=0

=> x=0 is extremum point

dh/dy=2(y-3)=0

=> y=3 is extremum point

dh/dz=2(z+1)=0

=> z=-1 is extremum point

Hence (0,3,-1) is the relative extrema point of this function

=> x=0 is extremum point

dh/dy=2(y-3)=0

=> y=3 is extremum point

dh/dz=2(z+1)=0

=> z=-1 is extremum point

Hence (0,3,-1) is the relative extrema point of this function
