An exponential function follows the general form of

Statement I tells us that there is only one term, so the  part of the equation isn't needed for this exponential function.

Statement II tells us that in this case, .

However, we could have nearly anything as our exponent. We are unable to make an accurate graph of this function, so more information is needed.
