The polynomial function f(x) = 3x - 2x + 7x models the motion of a roller coaster. the roots of the function represent when
the roller coaster is at ground level. which answer choice represents all potential values of when the roller coaster is at ground
level? begin by factoring x to create a constant term.

Multiplying an even number of negative numbers gives an answer that is choose from:
