Question 1017935: I am looking for the inverse function for f(x)= e^(2x).
I have found f^-1(x)=1/2 In(x), yet I can not find the others that also apply to this function and I am also unsure if f(x)=e^(2x) if the exponential function is its own inverse.
The choices are:
1. f^-1(x)= 1/e^(2x)
2. f^-1(x) log_2(x)
3.f^-1(x)= In√x
4. f^-1(x)= In(x^2)
Please help me with this problem.

Question 1018039: Hello there, I have a quiz tomorrow and I was wondering if you could help me find the x and y intercepts of a function. (Like written in f(x) style) All the tutorials I found online only deal with the equation if it is in a y = mx+b form, but I can't figure out how to how to do it if it is in something like a f(x) = 3x + 3 (just an example). Would I just treat the f(x) like y or would I do something else? Thank you in Advance
