Answer
$N=10$, $A=4$, $b=0.3$
Technology formula:$\qquad 10/(1+4*0.3^{\wedge}(-x))$
.
Work Step by Step
Comparing to
$\displaystyle \quad f(x)=\frac{N}{1+ab^{-x}}$
We get:
$N=10$, $A=4$, $b=0.3$
So, the technology formula is:
$10/(1+4*0.3^{\wedge}(-x))$
(We used the grapher at www.wanermath.com, as suggested by the book.)
