Chapter 1.1, Problem 5E

Reminder Round all answers to two decimal places unless otherwise indicated.

Note Some of the formulas below use the special number $e$, which was presented in the Prologue.

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, in pounds, at an age of a weeks, where a is 16 weeks or less. Then the predicted adult weight $W=W\left(a,w\right)$ in pounds, is given by the formula.

$W=52\frac{w}{a}$

a. Use functional notation to express the adult weight of a puppy that weighs 6 pounds at 14 weeks.

b. Calculate the predicted adult weight for the puppy from part a.
