Answer: NO, the given set of points does not represent a function.
Step-by-step explanation: We are given to check whether the set of points shown in the figure represent a function or not.
From the graph, we see that the set of points is
S = {(1, 1), (1, 2), (1, 3), (1, 4)}.
We know that
the set of ordered pairs (x, y) represents a function of no x co-ordinate is associated with more than one y co-ordinate.
For the given set of points S, we see that
the x co-ordinate 1 is associated to four different y co-ordinates 1, 2, 3 and 4.
So, the given set of points does not represent a function.
Thus, the required answer is NO.
