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.
Ramona needs to subtract the x -values from the f left parenthesis x right parenthesis -values. She will be able to prove that exponential functions grow by equal factors over equal intervals.

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.
Ramona needs to subtract the x -values from the f left parenthesis x right parenthesis -values. She will be able to prove that exponential functions grow by equal differences over equal intervals.

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.
Ramona needs to add another column to the table and find the change in f left parenthesis x right parenthesis -values. She will be able to prove that exponential functions grow by equal differences over equal intervals.

Answer 1

To address Ramona's objective, she needs to demonstrate the nature of exponential growth. The correct response 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 option is accurate because exponential functions are characterized by their growth being proportional (by equal factors) rather than additive (by equal differences) over equal intervals.
