If g(x) is the inverse of f(x) and f(x) = 4x + 12 , what is g(x)

Step-by-step explanation:

Ve have the function:

The first step to find the inverse is to exchange the variables, that is where we see put and  where we see put :

And we clear for the variable :

This would be the inverse of the function (since we know that ), and according to the problem the inverse of is , so:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to
