Final answer:
The value of f(4) from the given set of ordered pairs is 3, which corresponds to option A.
Step-by-step explanation:
The student has asked to find the value of f(4) given a set of ordered pairs: {(3,3), (4, 3), (5, 4), (6, 5), (7, 4)}. To find f(4), we need to locate the ordered pair where the first number (which represents the input or the 'x' value in a function) is 4. In the given set, the ordered pair with 4 as the first number is (4, 3). Therefore, the value of f(4) is 3, which corresponds to option A).
