A particle moves in one direction, stops, and then heads back in the opposite direction. The position of the particle (in meters) as a function of time is given by x(t) = -3.65t² + 4.52t + 7.91. What is the position of the particle at time t?

A) -3.65t² + 4.52t + 7.91
B) -3.65t² + 4.52t - 7.91
C) 3.65t² + 4.52t + 7.91
D) 3.65t² + 4.52t - 7.91
