Determine whether the function is one-to-one. If it is, find a formula for its inverse. f(x) = x2 - 8 Is the function one-to-one? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. Yes, the function is one-to-one. The inverse function is f'(x) =. (Simplify your answer.) O B. No, the the function is not one-to-one.

Describe how to find the inverse of a one-to-one function. Choose the correct answer below. O A. Replace f(x) with y in the equation for f(x). Interchange x and y. Solve for x. Finally, replace x by f *(x). -1 O B. -1 Replace f(x) with y in the equation for f(x). Interchange x and y. Solve for y. Finally, replace y by f *(x). OC. -1 Replace f(x) with x in the equation for f(x). Interchange x and y. Solve for y. Finally, replace y by f *(x). O D. Replace f(x) with x in the equation for f(x). Interchange x and y. Solve for x. Finally, replace x by f *(x). -1
