If the Function Is One-To-One, Find Its Inverse $$f ( x ) = x ^ { 3 } - 8$$

Multiple Choice

If the function is one-to-one, find its inverse. If not, write ʺnot one-to-one.ʺ
- $$f ( x ) = x ^ { 3 } - 8$$

A) not a one-to-one
B) $f ^ { - 1 } ( x ) = \sqrt [ 3 ] { x + 8 }$
C) $f ^ { - 1 } ( x ) = \sqrt [ 3 ] { x - 8 }$
D) $\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \sqrt [ 3 ] { \mathrm { x } } + 8$
