domain of the functions defined by this formulaf(x)=√x and g(x)=√((1-x))

Here are the graphs

If we exclude complex numbers, then the domain of f(x) is from 0 to infinity, because we can't take the square root of a negative number.

 

For the same reason the domain of g(x) is from negative infinity to 1.
