Answer:
a) The inverse of the function is 
b) The domain of the inverse function is C>1348.70.
Step-by-step explanation:
Given : The formula
, where
express the Celsius temperature C as a function of the Fahrenheit temperature F.
To find : a) A formula for the inverse function and interpret it.
b) What is the domain of the inverse function?
Solution :
a) The formula 
The inverse function of the given formula is the value of F.
Taking F to one side and rest term to other side,


Therefore, The inverse of the function is 
i.e. Fahrenheit temperature F as a function of the Celsius temperature C.
b) The domain of the inverse function.
We have given, 
Substituting in the formula,




The domain of the inverse function is C>1348.70.
