Answer
$N=8.5$, $A=3.25$, $b=1.05$
Technology formula:
$\qquad \text{ 8.5/(1+3.25*1.05^(-x)) }$
.
Work Step by Step
Comparing to
$\displaystyle \quad f(x)=\frac{N}{1+Ab^{-x}}$
we need $1+$ in the denominator, so we divide both the numerator and denominator with $2$.
$h(x)=\displaystyle \frac{8.5}{1+3.25(1.05^{-x})}$
We get:
$N=8.5$, $A=3.25$, $b=1.05$
So, the technology formula is:
$\text{ 8.5/(1+3.25*1.05^(-x)) }$
(We used the grapher at www.wanermath.com, as suggested by the book.)
