Multiple Choice

Find the inverse of the function.
- $$f ( x ) = 5 x ^ { 3 } + 7$$

A) $f ^ { - 1 } ( x ) = \sqrt [ 3 ] { \frac { x - 7 } { 5 } }$
B) $f ^ { - 1 } ( x ) = \sqrt [ 3 ] { \frac { x + 7 } { 5 } }$
C) Not a one-to-one function
D) $\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \sqrt [ 3 ] { \frac { \mathrm { x } } { 5 } } - 7$
