Help Please !!!! For the following exercises, find the f^-1(x) for each function. f(x)= x/x+2 I solved it like this : Am i correct? y= x /x+2 x=y/y+2 (y+2) (x) = y xy+2x= y - xy -xy 2x=y-xy 2x/1-x= y(1-x)/1-x Final answer : 2x/1-x= y But my solotuion book says the answer is -2x/1-x= y Is the answer 2x/1*x

what you did to get to this point is also right -2x/(1-x)= y
