    Post Instanteous Rate of Change

    Hi,
    I'm studying for my test right now, and I was thinking of possible questions that might be on the test... and then I came up with a question but I can't answer it. How could I possibly calculate the instanteous rate of change of an exponential function without graphing it?
    Thanks for the input.

    How would I find it if my function was 4^x for example?
    Thanks again.
