When you know the distance and the speed, and you want to know how long it will take you to get to your destination, you use the inverse of the aforementioned function. That is, division is the inverse of multiplication.
For example, think of a sports team. Each player has a name and a number. So if you knew a players name and wanted to know their number, you could think of this as a function from players to their numbers. Now, if you wanted to do the reverse, find a players name given their number, you would be using the inverse of this function
We use inverse functions in our daily lives all the time.
Answer:
First example:think of a sports team. Each player has a name and a number. So if you knew a players name and wanted to know their number, you could think of this as a function from players to their numbers. Now, if you wanted to do the reverse, find a players name given their number, you would be using the inverse of this function.
Second example: suppose I am travelling at 60 miles per hour, and want to know how far I have gone in x hours. Then this could be represented by the functionf(x) = 60 * x
Now I want to know the inverse: If I know I have travelled x miles how long have I been travelling for? f^{-1}(x) = x/60
