Answer 1

Foo! that's a good one! lol

Answer 2

Working on it

Answer 3

Well, we at least know that the domain can be any real number between -infinity and +infinity, so it has to be a or c

Answer 4

It's most likely a

Answer 5

ok, thank you!

Answer 6

This problem is interesting. So yeah the domain is definitely all real numbers. I don't get how the range could be either (-k,infinite) or (h, infinite). With really big negative numbers the a term wshould go to zero which makes me think the answer should be (k, infinite). I would guess a for this one but I really want to know why k is negative.

Answer 7

I agree. k should be positive, not negative
