Answer
$\mathrm{p}(2.5)=11.9$
The petrochemical production in Mexico, in the year ending with June 30, 2007 , is 11.9 billion metric tons.
Work Step by Step
Plot all the points, and join the neighboring points with line segments.
Graph a vertical line, x=2.5.
Estimate that the intersection is at p=11.9.
Interpret:
2.5 years after 2005, is midway through the year 2005+2=2007.
$\mathrm{p}(2.5)=11.9$
The petrochemical production in Mexico, in the year ending with June 30, 2007 , is 11.9 billion metric tons.
