    There is no function whose inverse is the zero function. Also, is the formula f(x) = ex or f(x) = ex? Your second question makes me think it might be the latter.
    As micromass already said, no we won't just give you the answer - this goes against the rules. To see the rules, click the Rules button near the top of the window and look at the section titled "Homework Help."
