<h2>
Explanation:</h2>
In this exercise, we have the following functions:

And they are defined for all real numbers x. So we have to write the following expressions:
First expression:

That is, we subtract s(x) from r(x):

Second expression:

That is, we get the product of s(x) and r(x):

Third expression:
Here we need to evaluate:

First of all, we find the sum of functions r(x) and s(x):

Finally, substituting x = -2:
