Since g(2) has an x value of 2, plug in 2 for x. Do 2(2)squared-2(2). That would be 4
This is an arithmetic sequence with first term -2007 and common difference of 1. and last term = 2009. Total number of terms = 2008 + 2009 = 4017
Sn = (n/2)(a + l)
Sum (4017/2) ( -2007 + 2009) = 4017 * 2 / 2 = 4017 Answer
