<em>Additional comment</em>
The value of f(x) for the function of problem 2 is 2.5^n for any value of x. That is, <em>the function value does not depend on x</em>, so it cannot be said to be an exponential function.
If you assume the definition of f(x) in problem 2 is a typo, then your answer will vary.
