I have a backpiling of great resources--I just can't seem to get around to them. Don't you just hate when that happens, lol? Glancing over Question A, I think I can do those. B kinda looks... odd. I don't immediately see how to solve it, but I'm sure it has to do with the fact that $f$ is continuous. C and, particularly, D look intimidating. Could you possibly explain what "image" means in this context? I'm honestly not familiar with the term. I'd say it's not nearly as complicated as it feels--you know? Things always look complicated if you don't know the terms being used, lol. BTW, is there any way you could post the test without the solutions? I find that my peripheral vision is startlingly good. I have a hard time trying to look at the questions intensely without seeing bits of the solutions.

I know one high school student who could pass this... guess I grew up in the wrong country! A few nitpicks... The solution to A2 supposes that f is defined as in A1 (= a^x), but the statement of A2 makes no such connection. In question C, use "its" for possessive (which is what you want). "it's" is a contraction for "it is" (which is a subject and a verb). In D, "Let f *be* ..." I've said it before: there's no way I could write such a test in a foreign language, so your work is remarkable to me!
