Answer:
B. The graph is not a function.
Step-by-step explanation:
We are given the graph of a relation.
It is required to determine whether the graph represents a function or not.
'Vertical Line Test' states that,
'If a vertical line passing through the graph of the relation cuts the graph at at-most one point, then the given graph represents a function else not'.
So, if we plot the vertical line 'x = 3' in the figure, we see that,
The vertical line drawn crosses the graph at two points A and B as shown below.
So, the graph fails the vertical line test.
Thus, the graph is not a function.
