  1. Oct 5, 2011 #1
    Can anyone help me answer this question?

    " Every exponential function is a geometric progression but not every geometric progression is an exponential function. Explain."

    It would be nice if you had some ideas you tried but couldn't get to work in your head.

    Think of it this way:
    Every human is a mammal, but not all mammals are humans.

    Basically, I just changed the objects, but the principle is the same. What does it imply if every human is a mammal? What does it imply if not all mammals are humans?
