Answer:
The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data is 
Step-by-step explanation:
Time (months) Views
0 50
2 313
4 1950
6 12,210
8 76,300
10 476,800



Slope =131.5


Slope =818.5
Since the slope is not same . So, it is not a linear relationship

Since the ratio between the consecutive outputs is same so, it is exponential relationship.
Formula : 
Where a is the initial value = 50
b = rate of change = 6.25
The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data
So
Dilation since then the lengths are changed. The image would then be only similar; not congruent.
