A small dog will weigh 22 pounds at adulthood. The following table shows the weight W, in pounds, t months after birth. The difference 
between his maximum weight and his current weight is given in the third row of the table.
t 3 5 7 9 11 W 7.48 12.99 16.12 17.15 18.37
14.52 9.01 5.88 4.85 3.63?
A: Use exponential regression to model the difference 
as a function of t. Round your answer to two decimal places.B: Use the model you found in part A to find a formula that gives the approximate weight W at age t months. Round your answer to two decimal places.C: Plot the graph of W versus t along with the data points for weight.D: At what age does the dog weigh 21.16 pounds? Round your answer to two decimal places.
