The ordered pair given in the bottom row can be written using function notation as; f(9) = 5
The function notation of a point (x, f(x)) or (x, y) is f(x) = y.
Now, from the definition of function notation, the function notation of the given ordered pairs of (2, 6), (7, 3) and (9, 5) are;
f(2) = 6
f(7) = 3
f(9) = 5
Thus, looking at the given options, the only one that represents the ordered pair written using function notation is f(9) = 5
