A 2D Cartesian graph with time t in seconds on the horizontal axis and velocity v in meters per second on the vertical axis. The horizontal axis ranges from 0 to 6 with labeled tick marks at 0, 1, 2, 3, 4, 5, and 6. The vertical axis ranges from -4 to 4 with labeled tick marks at -4, -2, 0, 2, and 4. A single solid piecewise linear curve begins at (0, 0), rises to (2, 4), decreases linearly passing through (4, 0), and ends at (6, -4). Thin dashed gridlines extend across all integer grid values. No other curves, text, or arrows appear.
Velocity \(v\) versus time \(t\) for the moving object.
An object moves along the \(x\)-axis. The graph shows the object's velocity \(v\) as a function of time \(t\). During which of the following time intervals is the object moving in the positive \(x\)-direction with decreasing speed?
