1. ## 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
