question 267

Essay

Experiments conducted by
A. J. Clark suggest that the response R(x) of a frog's heart muscle to the injection of x units of acetylcholine (as a percent of the maximum possible effect of the drug) may be approximated by the rational function
where b is a positive constant that depends on the particular frog. If a concentration of 40 units of acetylcholine produces a response of 40% for a certain frog, find the "response function" for this frog.
