Doctors sometimes need to calculate the body surface area of their patient when they are determining the specific dosage of a medicine they are administering. The formula for body surface area is B =, /H-W 3131 Where B is the body surface area in square meters, H is the height of the patient in inches, and W is the weight of the patient in pounds. 1. If the height of a patient is 68 inches, write a function B(W) that represents the body surface area of patients of that height. 2.

Doctors sometimes need to calculate the body surface area of their patient when they are
determining the specific dosage of a medicine they are administering. The formula for body
H•W
surface area is B = V3131
Where B is the body surface area in square meters, H is the height of the patient in inches, and W is
the weight of the patient in pounds.
1. If the height of a patient is 68 inches, write a function B(W) that represents the body surface
area of patients of that height.
2. Use technology(desmos.com) to find the graph and then sketch a graph of the function B(W)
þelow.

3. Interpret the domain, range, and increase/decrease of the graph in terms of the problem
situation.
