Answer:

Step-by-step explanation:
Here, we want to use the shape of the plot to give the appropriate value for n
From what we can see, there has been a rise from the left negative part towards the right positive part
What this simply indicates is that the value of n is positive even integer
We can deduce this further from the overall shape of the plot
If it was to be negative, we will have a partition-kind of plot view
