There is a formula that estimates how much your puppy will weigh when it reaches adulthood. The method we present applies to medium-sized breeds. First find your puppy's weight w at an age of a weeks, where a is 16 weeks or less. Then the predicted adult weight Ww = W(a, w), in pounds, is given by the formula
W = 52.".
In this exercise we consider puppies that weigh w = 9 pounds at age a.
(a) Write a formula for W as a function of the age a.
(b) Make a graph of W for ages up to 16 weeks.
