Determine the rate of change on the interval $(3,7)$ using the graph below:

Step 1 ：Determine the rate of change on the interval $(3,7)$ using the graph below:

Step 2 ：Without the graph or the y-values at x = 3 and x = 7, it's impossible to determine the rate of change.

Step 3 ：Therefore, the final answer is \(\boxed{\text{indeterminate}}\).
