What is the minimum value of the function f(x,y)= x^2+y^2 -y on the region where y greater or equal x^2 and y smaller or equal 1
f(x,y)= x^2+y^2 -y
Find partial derivative as
fx= 2x
fy=2y -1
To find critical point, set fx =0 and fy=0
2x =0, so x =0
2y-1=0, so y=1/2
Hence, critical point is (0, 1/2)
f(0, 1/2)= 0^2+(1/2)^2 -(1/2)= -1/4
minimum value of the function is -1/4

The average value of a function f(x, y, z) over a solid region E is defined to be fave = V(E) f(x, y, z) dv where V(E) is the volume of E. For instance, if p is a density function, then Pave is the average density of E.
