I need help please

Find "(x) and identify the domain and range of f". As a check, show that (1-1(x)) =1-(1(x)) =x. x+3 {( x) = X - 8 1- 3 (x) =0 (Type an exact answer, using radicals as needed.) What is the domain of f-1? (Type your answer in interval notation.) What is the range of f- 1? (Type your answer in interval notation.) Does f(f- 1(x)) =1 1(1(x)) =x? Find the intermediate forms of f(f 1(x)) and f-1(1(x). 1(1 1(x)) =[andf-1(f(x) =_ (Type expressions using x as the variable. Do not simplify.)
