The correct response is:
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 is because exponential functions exhibit a constant multiplicative rate of change, meaning that as \( x \) increases by equal intervals, the function values \( f(x) \) will be multiplied by the same constant factor.
