Problem 140 of 7
Compare average growth over interval [1,3] for models f(x) = x^3 and g(x) = 10x.
Hints
Using a hint is okay. It just tells the trainer to give you a little more review.

Full solution stays hidden until you ask for it.
1. Evaluate each model at both interval endpoints.
2. Compute each output change divided by input change.
3. Compare the average growth values.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Comparing only final values when average growth is requested.
