The path of a roller coaster over a particular lenght of track can be represented by a quadratic function f, where f (x) represents the vertical displacement above or below a support bar (in meters), and x represents the horizontal displacement to the left or right of a flagpole (in meters). The roller coaster dips below the support bar for values of x between - 2 and 1. Which function could represent f?

A. f (x) = (x-2) ^2+1

B. f (x) = (x+2) ^2+1

C, f (x) = (x-2) (x+1)

D. f (x) = (x+2) (x-1)
