- The horizontal axis represents time, denoted by \(t\).
- The vertical axis represents the value of the function.
- The graph depicts a solid curve representing the function \(\up{f}(t)[\up{u}(t-1) - \up{u}(t-3)]\) over time.
- Dashed lines are drawn vertically at \(t=1\) and \(t=3\), indicating the points where the argument of the unit step functions changes.
- For time values less than \(t=1\), the solid curve is negative and increasing as \(t\) approaches \(1\).
- Between \(t=1\) and \(t=3\), the solid curve continues to decrease until it reaches a minimum value, then begins to increase, appearing concave up.
- For time values greater than \(t=3\), the solid curve continues its upward trend, approaching the shape of the function \(\up{f}(t)\) multiplied by a constant value.
