1 Answered Questions for the topic Inverse Functions And Domain

When finding the inverse of f(x)=v(x-3) (a one to one function) and stating the domain and range of the inverse, why is the domain of the inverse switched?

So if f(x)=√(x-3), I know the original domain would be [3, ∞) and the range would be [0,∞), but what would the domain and the range be for the inverse be, which is f-1=x2+3, and why would it be... more
