Solve the problem.In a certain country the number of acres of farmland is modeled by 
where x is the year with 2002 ? x ? 2012. Evaluate f(2011) and interpret the result.
A. 759,448; In 2011, 759,448 acres of farmland are converted to other uses. B. 1,061,098; In 2011, there are 1,061,098 acres of farmland. C. 761,098; In 2011, there are 761,098 acres of farmland. D. 1,061,098; In 2011, 1,061,098 acres of farmland are converted to other uses.
Use synthetic division to divide f(x) by x - k for the given value of k. Then express f(x) in the form 
for the given value of k.f(x) = -5x4 + x3 + 2x2 + 3x - 1; k = 1
A. f(x) = (x - 1)(-5x3 + 6x2 - 4x - 1) B. f(x) = (x - 1)(-5x3 - 4x2 - 2x + 1) C. f(x) = (x - 1)(-5x3 + 4x2 - 2x - 1) D. f(x) = (x - 1)(-5x3 + 4x2 + 6x + 9)
