Answer:
800 pencils.
Step-by-step explanation:
We have been given that 5 students each brought in 8 boxes with 10 pencils per box.
The number of pencils in this group would be pencils.
Further, we are told that 10 students each brought in 8 boxes with 5 pencils per box.
The number of pencils in the 2nd group would be pencils.
Therefore, the students bring in 800 total pencils.

Then using the product rule, we get
We actually don't need to do any computation. By definition, the inverse function changes the role of input and output. So, if a function f maps x onto y, the inverse function maps y onto x.
You have to think like this: if the function makes a step further, the inverse function makes that same step back.
This means that the composition is always the identity function
. In fact,
So, for every function, you have
