Answer:
f(2)= 3.
Explanation:
When asking for f(2) from a graphic, we are being asked the following: "What value of y the graph shows when x is 2?" Therefore, let's look at the graph and find out (check the attached mage below).
Looking at the image, one could say that the graph has 2 values of y when x is 2, but in reality, the graph is telling you, by presenting the open or empty dot, that the bottom value isn't contained by the function. Therefore, the value of y when x= 2, is 3.
