Answer :
The function is an exponential growth function growth decay percent rate of change of the function is 110 %.
Given :
What type of exponential function is f(x)=0. 75(2. 1)^x what is the function's percent rate of change.
we know that,
exponential growth function in the form of y = a ( 1 + r )^x
on comparing both functions we get ,
1 + r = 2.1
r = 2.1 - 1
r = 21 / 10 - 1
= 21 - 10 / 10
= 11 / 10
= 1.1
converting into percentage:
= 1.1 * 100 %
= 110 %
