Показать описание
Inverse functions are simply functions that cancel each other out in some way. For example, they can help us convert values between units like Fahrenheit and Celsius. Inversing an inverse leads back to the original function.

How do we apply this Inverse function in real life problems?

She messed up the brackets as the 32 should not be in the bracket. The 32 is separate from the temperature. If it were part of it the nine fifths would change the 32 which is separate. It is clear if you compare 180 to 100 as 32 needs to be taken off 232 before you compare . Hence 180 is nine fifths of a hundred. You are doing this as zero is the same as thirty two in Fahrenheit .
