The correct response is:
c. 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 \( f(x) = a \cdot b^x \) exhibit multiplicative growth, meaning the ratio of the values at equal intervals will remain constant, which illustrates growth by equal factors.
