Best ResponseYou've already chosen the best response.0Hey to find the inverse of functions you got to do 4 steps. 1. Substitute f(x) with y. 2. Reverse the x and y variables. 3. Solve for y. 4. Replace y with f^1x

Best ResponseYou've already chosen the best response.0Everything's good but you accidentally wrote the last number wrong :) it's 2 :). Now can you do the 2nd step? ;)

Best ResponseYou've already chosen the best response.1So i add 2 to the other side

Best ResponseYou've already chosen the best response.0That's a bit later, but don't forget the 2nd step says to Reverse the x and y variables. Since our function is now y=1/3x2, we'd switch the x & y over, and it'd now be x=1/3y2 :) Do you get it so far? :)

Best ResponseYou've already chosen the best response.0and yeah on the 3rd step you'd then add 2 to both sides, & multiply by 3 to both sides as you're solving for y.

Best ResponseYou've already chosen the best response.1No I'm confused again likeep how can u divided 1/3

Best ResponseYou've already chosen the best response.0oh okay :) well we got x+2=1/3y To eliminate the 1/3, if we multiply it by it's reciprocal (opposite) which is 3, the 1/3 & 3 will cancel out leaving the y by itself :) and then we'd multiply 3 to the other side as well :) did you get that? :)

Best ResponseYou've already chosen the best response.0you multiply instead to cancel out the fraction by it's opposite number :)
