Document Summary
We"ll look at the graph of the function: y. It"s probably easier to find what isn"t in the domain. Functions like e x are continuous on all. The only possible problem here is with x. 0, so our composite function will also be x x. 0 , or in other words, all x such t hat x. Only bother with these i f they are reasonably easy to calculate. Here, they are especially easy: y - intercept x x - intercept y. 0 isn"t in the domain, so no intercept here. Vertical asymptotes (va) exist on our g raph is at lim. These are only going to occur at possible discontinuities, so the only place they could e. So we do have a vertical asymptote, but. Step #5 : examine f x f x. Notice, that exponentials are all positve, as is. "( ) < 0 ( x where it"s defined
