Answer 1

To prove something about how exponential functions grow, Ramona should focus on the growth patterns of the function values. Since exponential functions grow by equal factors over equal intervals, she needs to find the ratio of consecutive function values rather than the differences.

Therefore, the best choice would be:

**Ramona needs to add another column to the table and find the growth factors between the consecutive values of f(x). She will be able to prove that exponential functions grow by equal factors over equal intervals.**

This way, she can demonstrate that the ratio \( \frac{f(x_0 + \Delta x)}{f(x_0)} \) remains constant, confirming the nature of exponential growth.
