please be clear and give me the answer thank you

Watch the video that describes nding equations of inverses. Click here to watch the video. For the function tot) = 3x 5, determine whether f()r] is onetoone. It so, write an equation for the inverse function in the form y = f _ 1 {x}. Write an equation for the inverse function in the form 3r = f_ 1(x}. Select the corred choice below and, if necessary, ll in any answer boxes to complete your choice. A The function x} is one-to-one and f_1(}(} = D. ' (Simplify your answer.) Q B_ The function is not onetoone
