For Domain of Square root numbers always remember that the square root values should be greater or equal to zero but it can't be negative.. \[x \ge 0\] So Domain is all positive real numbers including 0 also.. But no negative numbers..

So the range would be [infinity, 0)?

let f(x) = y so, y = \(\sqrt{x}\) Square both the sides: \(y^2 = x\) Range is (infinity, -infinity)..
