## anonymous 5 years ago describe the domain of the function f(x,y)=√(y-x2).

1. anonymous

$\sqrt{y-x ^{2}}$

2. anonymous

What's under the radical cannot be negative. So, y - x^2 must be greater than or equal to 0. All points (x, y) that satisfy this requirement are in the domain of f(x, y).

3. anonymous

So basically a good answer is that the domain of the function is: $y \ge x^2$

thank you
