To determine which ordered pair is a local minimum of the function, f(x), we need to look for a point where the function value is smaller than the values of the function at the surrounding points.
From the table, we can see that the function value at x = 2 is -15, which is smaller than the function values at x = 1 and x = 3, which are both 0. Therefore, the ordered pair (2, -15) is a local minimum of the function, f(x).
Note that the ordered pairs (0, 9), (4, 105), and (-1, 0) are not local minima, as the function values at these points are all larger than the values at their surrounding points.
