1. An exponential growth or decay model is
given.

Determine whether the model represents growth or decay

Find the growth or decay factor

Find the growth or decay rate.

a. F(x)= 50(1.2)^x

b. Y=(1/3)^x

c. N(x)= 39.(2.8)^x

d. H(T)= (0.15)^T

e. M(t)= 3.5(0.7)^t

2. A patient is administered 250 mg of a therapeutic
drug. It is known that 40% of the drug is expelled from the body
each hour.

Find an exponential decay model for the amount of drug remaining
in the patient’s body after t hours.

Use the model to predict the amount of the drug that remains in
the patient’s body after 10 hours.
