Do the set of points in the figure represent a function? yes no

 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.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
