Best ResponseYou've already chosen the best response.1Hi friend, you just replace x by y and y by x to get the inverse function. and then solve for y . to your problem, when replace you have x= 3y + 9 > 3y =x9> y = (x 9)/3 or y = 1/3x 3 . that is inverse function of your function hope this help

Best ResponseYou've already chosen the best response.0so @Hoa our answer would be y=1/3x3
