Final answer:
The inverse function of f is f^-1 = {(5, −1), (0, 0), (6, 2)}. The value of f^-1(5) is −1.
Step-by-step explanation:
The given function f is {(−1, 5), (0, 0), (2, 6)}. To find the inverse of f, we swap the x and y values of each point. The inverse function f^-1 is {(5, −1), (0, 0), (6, 2)}. To find f^-1(5), we look at the x value in the inverse function that corresponds to the given value of 5. In this case, f^-1(5) = −1.
