The problem states:

A function f(x,y) is defined on the disc Q: x^2+y^2<=1 and equals 1 on it. The domain of f is D(f)=Q and f(x,y)=1 on Q.

The graph of the function is made of steel and hangs in the air. There is a flower at the origin and a few bees are in the air. There current positions are listed below.

Hint: If the bee is at the height z>1, where should is be in order not to see the flower?

Which of these bees can see the flower?

a) (4,5,6)

b) (2,3,4)

c) (6,6,9)

d) (0,1,2)

e) (2,1,3)

f) (1/3,1/3,1/3)

Not sure what this problem is asking, or how to start.
