Answer

$P(x)\approx 25.13(1.064)^{x}$

Work Step by Step

For small x, $f(x)=\displaystyle \frac{N}{1+Ab^{-x}}\approx(\frac{N}{1+A})b^{x}$ the logistic function grows approximately exponentially with base b. From the given model, $N=95.0,\ A=2.78, b=1.064$ so for small x, $P(x)\displaystyle \approx\frac{95.0}{3.78}(1.064)^{x}\approx 25.13(1.064)^{x}$ $P(x)\approx 25.13(1.064)^{x}$
