Question

What does the constant 0.2 reveal about the rate of change of the quantity?

Answer 1

In this problem, we have an exponential decay function

so

the function is of the form

`y=a(1-r)^x`

In this problem we have

`f(t)=310(0.2)^(24t)=310(1-0.8)^(24t)`

therefore

The answer is

The function is decaying exponentially at a rate of 80% every 24 days
