Answer 3

let f(x)=y, swap x and y, then solve for y (bring both sides to the power of 3) and see if that is a function, If so you can write it as f^-1(x)

Answer 4

sqrt(#) = #^(1/2)
so... the cubed root is #^(1/3)
(which you get rid of by raising each side the the equation to 3; cube each side)

Answer 5

x3+2
the three is an exponent thow

Answer 6

so do you get it
