Determine whether the following function is a one-to-one function. If it is one-to-one, list the inverse function by switching coordinates. f = {(-1, -1), (3, 3), (8, 5), (5, 8)} Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. f^-1 = { (Type an ordered pair. Use a comma to separate answers as needed.) B. f is not one-to-one

Step 1
A function is one-to-one if it never takes on the same value twice. That is, no two different inputs will produce the same output. Looking at the given function, we can see that each input corresponds to a unique output. Show more…
