Answer
$N=4$, $A=0.333$, $b=4$
Technology formula:$\qquad 4/(1+0.333*4^{\wedge}(-x))$
.
Work Step by Step
Comparing to
$\displaystyle \quad f(x)=\frac{N}{1+ab^{-x}}$
We get:
$N=4$, $A=0.333$, $b=4$
So, the technology formula is:
$4/(1+0.333*4^{\wedge}(-x))$
(We used the grapher at www.wanermath.com, as suggested by the book.)
