Chapter 11.4, Problem 75E

Crude Oil Prices The price per barrel of crude oil in the period 1980–2013, in constant 2014 dollars, can be approximated by

$P\left(t\right)=0.27{\left(t-1980\right)}^2-8.6\left(t-1980\right)+93\text{ dollars }\left(1980\le t\le 2013\right),$ where t is the year.³⁰ Find $P\text{'}\left(t\right)\text{ and }P\text{'}\left(2010\right)$. What does the second answer tell you about the price of crude oil?
