Best ResponseYou've already chosen the best response.0umm we have to find inverse first which is x+8/4=y and graphing it gives me dw:1333411085687:dw

Best ResponseYou've already chosen the best response.0\[\Large f^{1}(x) =\frac{1}{f(x)}\] ... so that should be . .\[\LARGE f^{1}(x)=\frac{1}{4x8}\] is it??

Best ResponseYou've already chosen the best response.0I don't know it either... but tell me, how do you get x+8/4=y ... show me steps I want to see them if it's possible ! O_O

Best ResponseYou've already chosen the best response.0y=f(x)=4x8 x=4y8 (switched) x+8/4=y (solve for y)

Best ResponseYou've already chosen the best response.0still dizzy... I don't know.. OK now tell me if we have \[\LARGE f(x)=\frac{1x}{1+x}\] how does f^{1} go?

Best ResponseYou've already chosen the best response.0ok I guess I'm wrong, but I want to learn it.. :(

Best ResponseYou've already chosen the best response.1To find the inverse, switch x and y, and write in terms of y.

Best ResponseYou've already chosen the best response.0f(x)=1x/1+x x=1y/1+y x(1+y)=1y x+xy=1y y=1x+xy

Best ResponseYou've already chosen the best response.1y = (1  x)/(1 + x) Switching the x and y: x = (1y)/(1+y) x + xy = 1  y y(1+x) = 1x y = (1x)/(x+1)

Best ResponseYou've already chosen the best response.1That's y=x yes. Best way to see it is to draw the line, then folding the paper over y=x and to see how the graph reflects

Best ResponseYou've already chosen the best response.1Noo... you flip the function f(x) over the line y=x.

Best ResponseYou've already chosen the best response.1... I honestly don't know how you got that. Look at my graph. Thats how f, y=x and f^1 looks like

Best ResponseYou've already chosen the best response.0that was for f(x) and if I reflect it, i'll get dw:1333413484096:dw
