Answer:
f(2) = 3
Explanation:
You want the value of f(2), given the graph of f(x).
Function value
The value of the function for a given argument is found by locating the point on the graph with an x-coordinate equal to the argument. The y-coordinate of that point is the function value.
See the attachment.
The y-coordinate associated with the point that has an x-value of 2 is 3.
f(2) = 3
