Best ResponseYou've already chosen the best response.2is the original function \[\Large f(x) = \frac{3}{x2}\] OR \[\Large f(x) = \frac{3}{x}2\]

Best ResponseYou've already chosen the best response.2y= 3/(x2) x= 3/(y2) ... swap x and y, now solve for y x(y2)= 3 x*y2x = 3 x*y = 3+2x y = (3+2x)/x

Best ResponseYou've already chosen the best response.2So the inverse is \[\Large f^{1}(x) = \frac{3+2x}{x}\]
