The function y = 4(.97)^x is a decay function by 3%
From the question, the equation of the function is given as
y = 4 (.97)
Rewrite the equation properly
So, we have the following representation
y = 4(.97)^x.
The above function is an exponential function
An exponential function is represented as y = ab^x
When y = 4(.97)^x and y = ab^x are compared, we have the following representation
b = 0.97
The value of b in this case is the factor
Also, if b is less than 1, then the function is a decay function
0.97 is less than 1
So, the function represents a decay function
The decay percentage is then calculated as
Decay = 1 - b
So, we have
Decay = 1 - 0.97
Evaluate
Decay = 0.03
Express as percentage
Decay = 3%
Hence, the function decays by 3%
