f(x)=√x2
Find the domain of the function is it x2
the range of function is it (00,2)
the domain of the inverse is it x>2
The range of the inverse is it (2,00)
Thanks

for the domain, we know that √u must have u>=0, so we need x2>=0, or x>=2.
the range is [0,oo)
domain and range are switched for the inverse
