What is the domain of f(x,y) = sqrt x + sqrt y

[From: ] [author: ] [Date: 11-06-13] [Hit: ]
infinity),no negative numbers allowed else ur expression becomes imaginary.......
f(x,y) = √x + √y

How can I find the domain of this function ?

-
domain of f is the set of all real numbers variable x and y can take such that the expression defining the function is real,therefore the domain of f(x,y)may be given as (0,infinity),no negative numbers allowed else ur expression becomes imaginary.
