Best ResponseYou've already chosen the best response.2replace f(x) with "y" so its y = (3  2x)/4

Best ResponseYou've already chosen the best response.2and then switch x and y .... so u will get x = (3  2y)/4 and then solve for y

Best ResponseYou've already chosen the best response.0so for solving for y we do dw:1442232845898:dw

Best ResponseYou've already chosen the best response.2hmmm see. x = (3  2y)/4 multiply 4 onn both sides.... u will get 4x = 3  2y so 3  4x = 2y now get y

Best ResponseYou've already chosen the best response.2then 3  4x = 2y so y = (3  4x)/2
