For the function f(x)=2x-9, determine whether fix) is one-to-one. If so, (a) write an equation for the inverse function in the form y = f(x). (b) graph f and f" on the same axes, and (c) give the domain and the range off and f is not one-to-one, say so. (a) Write an equation for the inverse function in the form y=f(x). Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice. OA. The function f(x) is one-to-one and f(x)-(Simplify your answer.) OB. The function is not one-to-one. if the function
