1. The problem asks to create a graphic where acceleration $a_x$ is the dependent variable and time $t$ is the independent variable, based on the given velocity-time graph.
2. Recall that acceleration is the rate of change of velocity with respect to time, mathematically expressed as:
$$a_x = \frac{\Delta v_x}{\Delta t}$$
3. We analyze the velocity graph in segments to find acceleration in each interval:
- From $t=0$ to $t=2$ seconds, velocity decreases from 0 to -4 m/s.
$$a_x = \frac{-4 - 0}{2 - 0} = \frac{-4}{2} = -2 \text{ m/s}^2$$
- From $t=2$ to $t=4$ seconds, velocity increases from -4 to 4 m/s.
$$a_x = \frac{4 - (-4)}{4 - 2} = \frac{8}{2} = 4 \text{ m/s}^2$$
- From $t=4$ to $t=6$ seconds, velocity remains constant at 4 m/s.
$$a_x = \frac{4 - 4}{6 - 4} = \frac{0}{2} = 0 \text{ m/s}^2$$
4. The acceleration-time graph is therefore piecewise constant with values:
- $a_x = -2$ m/s$^2$ for $0 \leq t < 2$
- $a_x = 4$ m/s$^2$ for $2 \leq t < 4$
- $a_x = 0$ m/s$^2$ for $4 \leq t \leq 6$
5. This graph can be represented as a step function with these values over the respective time intervals.
