Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. what multiplicative rate of change should hal use in his function?

0.98

Step-by-step explanation:

The exponential decay function is given by :-

, where A is the initial amount, r is the rate of decay in t years.

Given: The initial am=mount = $10,000

The rate of decay=2% =0.02

Then, the exponential function to represent the value of a $10,000 investment decreasing at 2% annually for t years is given by :-

Here we can see is multiplied with the initial amount for all t=0,1,2,3,.....

At t=0, f(0)=10,000

At t=1, f(1)=10,000(0.98)

The multiplicative rate of change should Hal use in his function=

i got 86 for this

hope this !

if you need an explanation just ask
