I am aware of that but how would I go forth in solving the whole equation ?

Thanks EP,

I will check your answer Jenny.

 

I think this is your question. It is hard to read.

 

\(f(x)=\frac{8}{1+3e^{-0.7x}}\\ f(-1)=\frac{8}{1+3e^{0.7}}\\\)

 

8/(1+3*e^0.7) = 1.1361605924567683 = 1.14   (to 2 decimal places or 3 significant figures)

 

So Congratulations Jenny, you got it right :)
