For the following function defined that is one-to-one, write an equation for the inverse function in the form y=f1(x), and then graph f and f1 on the same axes. Give the domain and range of f and f1. If the function is not one-to-one, say SO. f(x)=4+x, x-4 OA. f(x)= , x0 OB. f(x)= , X0 C. The function is not one-to-one. If the function is one-to-one, graph f and f1. If the function is not one-to-one, just graph f. Choose the correct graph below. The solid curve shows the graph of f and the dotted curve shows the graph of f if applicable. A. O B. The domain of f is (Type your answer in interval notation.) C. G OD.
