Question 1
Find the inverse of 
Explanation: To find the inverse of a function swap the variables and solve for 
. The function and its inverse when multiplied together, equals one. This means that the inverse undoes the function.
For this particular function the inverse is found as follows.
First, switch the variables.
Now, perform algebraic operations to solve for 
.
Therefore, the inverse is
