Find the domain of the function. Write your answer in interval notation. (If you need to enter ∞ or -∞, type INFINITY or -INFINITY.)

Question

h(u,v) = sqrt(4-u^2-v^2)

u^2+v^2 = ?

Answer 1

surely you know that the domain of
√x is x>=0

so, here you have √(4-(u^2+v^2))
so you need
4-(u^2+v^2) >= 0
