CAFFEINE Suppose an 8-ounce cup of coffee contains 100 milligrams of caffeine. The rate at which caffeine is eliminated from an adult’s body is 11% per hour. The function f(x)=100(0.89)to the power of x
can be used to model the amount of caffeine left in a person’s bloodstream after x hours of consuming the cup of coffee. Suppose the function g(x)=25(0.89)to the power of x
represents the amount of caffeine left in a person’s bloodstream after x hours of consuming an 8-ounce cup of green tea. Describe g(x) as a transformation of f(x).
