6. For the following parts let f(x) =- +. I Assume the domain of f is [-1, 0) U [1, co). (a) (10 points) Find the inverse of f(r) (hint: use the quadratic formula to solve for y). Why is it necessary to restrict the domain of f?(b) (6 points) Find the domain and range of f-(x). What is the range of f? Your explanation should not use a graph (please feel free to use a graph to check your work)
