Consider the graphs of $f(x)$ and $g(x)$ below: For each interval given below, decide whether the average rate of change of $f(x)$ or $g(x)$ is greater over that particular interval.

1. $0 \leq x \leq 4$ ? f g both have an equal rate of change
2. $0 \leq x \leq 8$ ? f g both have an equal rate of change
3. $0 \leq x \leq 2.2$ ? f g both have an equal rate of change
4. $5.2 \leq x \leq 6.1$ ? f g both have an equal rate of change
5. $5.2 \leq x \leq 6.9$ ? f g both have an equal rate of change
