Question

Find the inverse of the function. f(x) = cube root x/8 -4

Answer 1

is that \(f(x)=(\sqrt[3]x/8) -4\) ?

Answer 2

\[f(x)=\sqrt[3]{\frac{ x }{ 8 }}-4\]

Answer 3

oh, ok
to get the inverse
let y= f(x)
and interchange 'x' and 'y'

Answer 4

just solve for x and at the end swap x and y.

Answer 5

\(y= \sqrt[3]{\dfrac{x}{8}}-4\\x= \sqrt[3]{\dfrac{y}{8}}-4\)
solve for 'y' !
can you ?
