Question

Write the exponential function that describes the situation.

The initial amount of the function is 11 and then it decreases by a factor of 8/9 with each unit increase in x

The function that describes the situation is y=

Answer 1

Answer: The form for an exponential equation is f(t)=P0(1+r)t/h where P0 is the initial value, t is the time variable, r is the rate and h is the number needed to ensure the units of t match up with the rate. Plug in the initial value for P and the rate for r. You will have f(t)=1,000(1.03)t/h.
