f(x) = 

f(x) = 

f(x) = 

f(x) =

Answer 1

I would assume all of them since they are all the same, here is an example of exponential decay : Write an equation for the following statement, Merida has has $200,000 in a stock market which is decreasing by 1% annually.

f(x) = 200000(.99)^2

Comment if you need me to explain why this is the equation
