What does the inverse of this function represent?

0 votes

I'm given the function for Celsius temp in terms of Fahrenheit temp:

C(F) = 5/9 (F - 32) when F is greater than or equal to -459.6

I found the inverse function like this. I first shuffled around the function so that it was
F = 32 + (9 C)/5

and then I switched F and C to get the inverse function:

C(F) = 32 + 9F/5

The question asks what this inverse function I just found ^ represents:

A) The inverse represents the temperature 1/F corresponding to a temperature C. 
B) The inverse represents the temperature F corresponding to a temperature C.
C) The inverse represents the temperature C corresponding to a temperature F. 
D) The inverse represents the temperature 1/C corresponding to a temperature C.
