Answer
$F=\frac{9}{5}C+32$ where $C\geq-273.15$
This is Fahrenheit temperature as a function of Celsius temperature.
Work Step by Step
$C=\frac{5}{9}(F-32)$, where $F\geq-459.67$
$F-32=\frac{9}{5}C$
Inverse function: $F=\frac{9}{5}C+32$
$\because F\geq-459.67, C\geq\frac{5}{9}(-459.67-32)=-273.15$
This is Fahrenheit temperature as a function of Celsius temperature.
