1. The problem statement, all variables and given/known data Solve y=f(x) for x. What is the range of f? Your expression for x in terms of y may be helpful to verify your statement. f(x) = sqrt(x/(4-x)) 2. Relevant equations 3. The attempt at a solution I solved for x and got x = 4y^2/(1+y^2). I would like to know if this is correct or not also would the range of this be the domain of the original function because we had to find the domain in an earlier part of the question.
