The exponential model would take the form:
A, the initial value is 2, we will use 3 days and 8 tops to find k, or the rate.
Now, plugging in 6 days:
The linear would take the form:
y = mx+b
First the slope would be: (8-2)/(3-1) = 3
And to find b we could plug in the point (8,3):
8 = 3(3)+b
b = 8-9
b = -1
y = 3x-1
At x=6
y = 3(6)-1
y = 17
Thus, the exponential is almost double the result of the linear! Hope that helps.
