I need to know the range

Find f(x) and identify the domain and range of f. As a check, show that (1 7 ( x ) ) = 1- ' (f ( x ) ) = x . 1 f ( x ) = - 6/5 f ( x ) = X (Type an exact answer, using radicals as needed.) What is the domain of f- 1? (0,co) (Type your answer in interval notation.) What is the range of f- 1? (Type your answer in interval notation.)
