Functions: Adding and Subtracting
In this video I discuss adding and subtracting functions.
Here we look at finding (f + g) (x) as well as ( f - g ) (x) and (f - g)(4).
I show how to simplify and evaluate all of the functions after combining.
This would be a topic one would see early on in an Algebra or PreAlgebra class.
