Question

Find the inverse of the function.
f(x) = x3 - 8

Not a one-to-one function
f-1(x) = cube root of x plus eight
f-1(x) = cube root of quantity x minus eight
f-1(x) = cube root of quantity x plus eight

Answer 1

To find the inverse of a function:

change f(x) to y
switch y to x and the x to a y
solve for y

Answer 2

so

y = x^3 -2^3

Answer 3

It's x^3

when people copy paste the question \(x^3\) becomes x3

Answer 4

\[y=x^3−8\]
\[x=y^3−8\]
\[x+8=y^3\]
\[y=\sqrt[3]{x+8}\]
