Let f(x)=10/1+4e^-0.05x

Question

What are the values of L,a and k

what is the long term behavior?

how long does it take the function to get a value of 99% up to 99.5% of its long term value

Answer 1

I am GUESSING that you intend this to be a logistic function, in which case the entirety of the expression following the / symbol MUST be enclosed in parentheses. (This is because the WyzAnt platform does not have the capability of a long horizontal dividing symbol, such as one might write on paper.)

 

Once you agree to my observation, you can solve for x in 9.9 = f(x)

and solve for x in 9.95 = f(x) and the difference in these two values for x is "how long" it takes.
