Practice Problems for 2/27
Based on information collected about Body Mass Index, one study found that the percentage of the US population which is considered obese (according to their BMI) is given by
\[
P(t)=\frac{4}{10^4}t^3+\frac{36}{10^4}t^2+\frac{8}{10}t+12,\quad 0 \leq t \leq 13.
\]
(So the study covers a 13 year period.)
The study advocates a drastic changes to laws concerning school cafeterias and PE programs, as well implementing things like a sugar tax, stating,
"Not only is the population of obese individuals increasing, but the rate at which the US population is becoming obese is also rising."
Based on the information provided by the study is this statement true or false?
