    Exponential functions asymptote

    I have a question, which was not stated in my worksheet now that I'm reading it.

    When we have an exponential function, we can express it as the following

    f(x) = ab^x
    a cannot = 0, b cannot = 1 b > 0

    According to Sparknotes if I comprehended the concept, "
    The graph has a horizontal asymptote at y = 0
    , because 2x > 0 for all x", does this mean the asymptote is always 0 ?

    By the way my worksheet does not say vertical or horizontal asymptote, it simply says find the asymptote.

    Well I can see that people like me are the ones that create more work and confusion for others. While reading more through my assignment I found the following equation.

    y = ab^x^-^h+K

    K being the horizontal asymptote
