Answer:
Predicted values:








Residuals:








Step-by-step explanation:
For this case we assume the following exponential function:

Where x represent the hours and y the predicted values for each hour. We can find the estimated values like this:








Now we can find the residuals with this formula:

And replacing we got:








Using technology, the regression equation is
y=9.08292(1.09965)ˣ.
The number of recommendations after 60 days is 2113.277 ≈ 2113.
Explanation
I used Desmos to graph the points, then entered the expression y₁~a*bˣ to calculate the regression.
I then substituted 60 in for x in the regression equation to get the answer of 2113.
