Answer:
The graphs shown is NOT a function.
Step-by-step explanation:
We can use Vertical Line test to determine whether a given relation in the graph is a function or not. A relation is a function if one input results in only one output. If we draw vertical lines on the graph, and any of these vertical line intersect the graph at 2 or more positions, then it means that for one value of x, there are 2 values of y. Hence, for one input, there are more than one outputs. Therefore, the relation will not be a function.
We can see in the attached graph below that any vertical line intersects the graph at 2 positions. Hence, the given relation is graph is not a function.
Apologies for the rough drawing.
You can apply the same technique for the graph of the relation which is not shown, you'll get your answers to fill in the blanks
