E: as x -> + ∞, f (x) → 0

F: as x -> - ∞, f (x) → - ∞

Answer 1

Hi Dan H.,

It's not possible to be sure that the graph I'm looking at is what you intended to input.

But it appears that f(x)-> +.infinity. as x-> -.infinity. (that's (D), and maybe f(x) -> -.infinity. as x -> +.infinity. I say maybe, because no portion of the function is shown at f(x) <0, so it's not clear if the function continues along on the x-axis as x increases, or just drops out of sight. It would have been better to include both x- and y-axes, as well as the function with a different notation than reverse slashes.

It's possible to import graphs into Wyzant; but Customer Service is strangely reticent as to how this may be successfully done. The best hint I have is, look around until you find a query with a nice graph displayed, then post a comment to it, asking how, and wait. (you can't just email tutors by their Wyzant names. I imagine you can figure out why).
