After the expression is simplified as much as possible, x is raised to the exponent 2
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
You have to integrate two equations, one for the case where the value in the absolute signs is negative and one for the case where the value is positive...
So you will integrate one on the interval 0 to 1 and the other on the interval from 1 to 3...
⌠-x+1 dx, x=[0,1] + ⌠x-1 dx, x=[1,3]
(-x^2/2+x)[0,1] + (x^2/2-x)[1,3]
(-0.5+1)+(4.5-3-0.5+1)
(0.5)+(2)
2.5 u^2
