I got help for this problem before, but just checked and it's not correct.
What am I doing wrong with this problem?
f(x)=3sqrt(5x)+3
y=3sqrt(5x)+3
3sqrt(5x)=y3
(3sqrt(5x)^3=(y3)^3
5x=(y3)^3
x=(y3)^35

Best ResponseYou've already chosen the best response.0y = 3rt(5x) + 3 ; i assume you wanna invert it x = (5y)^(1/3) + 3 x3 = (5y)^(1/3) (x3)^3 = 5y (x3)^3 5 = y (x3)^3 +5 = y

Best ResponseYou've already chosen the best response.0y = 3rt(5x) + 3 ; x = (5y)^(1/3) + 3 These two are not same! even not inverses of each other!

Best ResponseYou've already chosen the best response.0y = cbrt(5x) + 3 ; we can usually find the inverse by swapping x and y ; and resolving for y. x = cbrt(5y) +3 x3 = cbrt(5y) ; ^3 each side... (x3)^3 = 5y ; +y and (x3)^3 to both sides y = 5 (x3)^3 which is exaclty the same as: y = (x3)^3 + 5 which sauhkik says aint the solution lol

Best ResponseYou've already chosen the best response.0cbrt(5y) = (5y)^(1/3) they are the exact same thing..
