Determine Whether the Given Function Is One-To-One $$f ( x ) = x ^ { 3 } - 8$$

Multiple Choice

Determine whether the given function is one-to-one. If so, find a formula for the inverse.
- $$f ( x ) = x ^ { 3 } - 8$$

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