Write an equation for the function and label as exponential growth or exponential decay. (1, 10) (0, 5) If the data below are from an exponential function, what is the value of a? 143

Rewrite the exponential equation as a logarithm. (Use capital letters for J, R, C, and D.) bJR = C − D

Veterinarians use different medications to treat fleas in dogs. Once administered, the medication typically decays exponentially. One treatment decays by half each week. A dog receives 4 mL of medication and the function f gives the number of mL of medicine left after w weeks. 1. Find the amount of medication in the dog's bloodstream 1 week, 2 weeks, and 3 weeks after it is administered. 2. Write an expression to represent the amount of medication in its bloodstream 1 day after it is administered. 3. Explain what f () means in this context.
