A 2D line graph with a horizontal axis labeled t and a vertical axis labeled x. The origin is at (0,0). A single continuous solid curve begins at the origin with a positive slope, curves downward to reach a smooth local maximum at t_1, decreases through an inflection point at t_2 where the slope is most steeply negative, flattens out to reach a smooth local minimum at t_3, and curves upward with increasing positive slope through t_4. Vertical dashed lines drop from the curve at times t_1, t_2, t_3, and t_4 to tick marks labeled t_1, t_2, t_3, and t_4 on the horizontal axis. No other labels, lines, text, or axes appear.
Position x versus time t for an object moving in one dimension.
An object moves along the x-axis. The graph shows the position x of the object as a function of time t over the interval from t = 0 to t = t_4, with an inflection point occurring at t = t_2. Which of the following statements correctly describes the motion of the object?
