take a look at this, letting a=5, b=3 http://www.wolframalpha.com/input/?i=y+%3D+3*5%5Ex
so when x= large negative number, then slope goes to ....
Describe when the graph of f(x) = ab^x is a horizontal line.?
I thought it was when a=0, but its not...

a=0 or
b=1
But it will approach a horizontal asymptote otherwise, as Reiny suggests.
