Drug Dosage There are several rules for determining doses of medicine for children when the adult dose has been specified. Such rules may be based on weight, height, and so on. If A is the age of the child, d is the adult dose, and c is the child’s dose, then here are two rules:

At what age(s) are the children’s doses the same under both rules? Round your answer to the nearest year. Presumably, the child has become an adult when c = d. At what age docs the child become an adult according to Cowling’s rule? According to Young’s rule? If you know how to graph functions, graph both and as functions of A, for A ≥ 0, in the same plane. Using the graphs, make a more informed comparison of Young’s rule and Cowling’s rule than is obtained by merely finding the age(s) at which they agree.
