How many values can be found for f(3)?

The graph of f(x) is shown above.

How many values can be found for f(3)?
A . 0
B . 1
C . 2
D . 4
E . Cannot be determined.

Answer: B

Explanation:

Be careful C the question asks you for the number of values of f(3) not f(x) = 3. In other words, how many y values can be generated when x = 3? If the line x = 3 is drawn on the graph, it passes through only one point. There is only one value for f(3).
