Best ResponseYou've already chosen the best response.0i don't think you can do it because as soon as you try to get that x out of the exponential, you lock the other x in a log do you know if there is an answer and what that answer is? if so i can try to hack it or you can bump and wait for someone else to come along to complicate matters, the other thing is this fails the socalled Horizontal Line Test  there is a local maximum, as you can see from the attached, so for f(x), 2 x's can map to the same y; but the inverse would require the opposite, ie that 1 y maps to 2 x's so there is no function so that you would need to restrict the domain to the LHS or RHS of the turning point .... not that helpful, i know :p

Best ResponseYou've already chosen the best response.0Wel the the multiple choice answers provided for this question are: A. f^1(x)=3x2 B. f^1(x)= 3/4x+2 C. f^11(x)=4/5x D. f^1(x)=4/5x+3/4 I'm just not sure of the answer.

Best ResponseYou've already chosen the best response.0none of these give you an inverse to what you posted maybe you should post the actual question or a screenshot. i think that could help greatly.
