The total number of identity theft cases, solved and unsolved, from 2005 through 2010 can be represented by the function F(x) = 0.0584 +2.175x3 +
340.2x2 - 1,500x + 20,000, where x represents the number of years since 2005.
A task force is assigned to help prevent identity thefts. The task force uses the
function g(x) = 0.0052X2 + 200.517x2 + 300x + 10,000 to describe the number of
identity theft cases that have been solved from 2005 through 2010, where x
represents the number of years since 2005. How many identity theft cases
remain unsolved in 2007 based on these function models?

A.29,781
B.8,438
C.5,128
D.6,977
