Responses

A: Ramona needs to add another column to the table and find the change in f(x)-values. She will be able to prove that exponential functions grow by equal differences over equal intervals.
B: Ramona needs to subtract the x-values from the f(x)-values. She will be able to prove that exponential functions grow by equal factors over equal intervals.
C: Ramona needs to subtract the x-values from the f(x)-values. She will be able to prove that exponential functions grow by equal differences over equal intervals.
D: 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.

Answer 1

The correct response is:

D: 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 have the property that the ratio of consecutive outputs (f(x)-values) remains constant when the inputs (x-values) are changed by equal increments, indicating they grow by equal factors.
