Answer:

f(2) = 7/4

Step-by-step explanation:

$f(x) = \frac{2x + 7 - {x}^{2} }{4} \\ f(2) = \frac{2(2) + 7 - {2}^{2} }{4} \\ f(2) = \frac{4 + 7 - 4}{4} \\ f(2) = \frac{7}{4}$

Answer: $\bold{D.\ \bigg(-\infty, \dfrac{ln\ 4}{0.2}\bigg)}$

<u>Step-by-step explanation:</u>

$y=\dfrac{c}{1+ae^{-rx}}\qquad \text{where growth rate increases from}\ -\infty\ to\ \dfrac{ln\ a}{r}$

$f(x) = \dfrac{15}{1+4e^{-0.2x}}\qquad \rightarrow \qquad a=4, r=0.2$

$\text{So, the growth rate increases over the interval}\ \bigg(-\infty, \dfrac{ln\ 4}{0.2}\bigg)$
