Write an exponential decay function to model the situation. Compare the average rates of change over the given intervals.
initial value: 47
decay factor: 0.8
1≤x≤4 and 5≤x≤7
The exponential decay function to model the situation is f(x)= 47(0.8)*
The average rate of change over 1≤x≤4 is The average rate of change over 5≤x≤7 is
(Round to three decimal places as needed.)
The rate of change
