Final answer:
Evenly spaced data cannot be modeled by an exponential function if successive quotients are all the same.
Examination
If the consecutive quotients are all the same, then an exponential function is not a good fit for modeling data that is equally spaced. The difference between successive inputs is not constant in an exponential function, but the quotient between any two successive outputs is. Alternatively, if the difference between consecutive inputs is consistent, a linear function can be used to simulate evenly spaced data. Consequently, it is untrue to say that an exponential function can represent evenly spaced data if all of the subsequent quotients are the same.
