Oil Production in Mexico Crude oil production by Pemex , Mexico’s national oil company, for 2008–2013 could be approximated by P ( t ) = 0.017 t 2 − 0.4 t + 5.23 million barrels per day ( 8 ≤ t ≤ 13 ) where t is time in years since the start of 2000. 4 According to the model, approximately when was oil production by Pemex least? What was the oil production at that time? (Round the answer to two significant digits.) [ HINT: See Example 1.]
