Question

Help finding f^-1(x)

Answer 1

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

Answer 2

write it like y= \(\sqrt[3]{x-8}\)
then cube both sides, what u get ?

Answer 3

cube each side?

Answer 4

so f^-1 would look like

y = cubed root of x - 8
x = cubed root of y -8

so you would cube both sides

x^3 = y-8
add 7 to both sides

y = x^3 + 8 ??

Answer 5

that seems correct to me.
good work :)

Answer 6

oh wow lol thanks!
