The formula F (C) = 9 5 C + 32 calculates the temperature in degrees Fahrenheit, given a temperature in degrees Celsius. You can find an equation for the temperature in degrees Celsius for a given temperature in degrees Fahrenheit by finding the function's

F (c) = 95 c+32

for example, when we want to convert 30 degrees Celsius to Fahrenheit, we calculate F (30) = 95*30+32 = 2882

So to convert from Celsius to Fahrenheit we multiply by 95 and then add 32.

So given a value in Fahrenheit to Celsius we reverse the operations, that is given a value F, to find the temperature in Celcius, we subtract 32, then we divide by 95.

In functional notation: C (F) = (F-32) / 95

Answer: C (F) = (F-32) / 95
