The Function F Is One-To-One $$f ( x ) = ( x + 7 ) ^ { 3 }$$

Multiple Choice

The function f is one-to-one. Find its inverse.
- $$f ( x ) = ( x + 7 ) ^ { 3 }$$

A) $\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \sqrt { \mathrm { x } } - 7$
B) $f ^ { - 1 } ( x ) = \sqrt [ 3 ] { x } + 7$
C) $\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \sqrt [ 3 ] { \mathrm { x } } - 7$
D) $\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \sqrt [ 3 ] { \mathrm { x } } - 343$
