question 424

Multiple Choice

Find a formula for the inverse of the function described below.
- $32 ^ { \circ }$ Fahrenheit $= 0 ^ { \circ }$ Celsius. A function that converts temperatures in Celsius to those in Fahrenheit is $f ( x ) = \frac { 9 } { 5 } x + 32$

• A) \(\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \frac { 9 } { 5 } \mathrm { x } + 32\)
• B) \(\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \frac { 5 } { 9 } ( \mathrm { x } - 32 )\)
• C) \(f ^ { - 1 } ( x ) = \frac { 5 } { 9 } ( x + 32 )\)
• D) \(f ^ { - 1 } ( x ) = x + 32\)
