How to Add and Subtract Functions

We can add and subtract functions just like we can add and subtract numbers. For instance, if we had two functions, \(f(x)\) and \(g(x)\), we could make two new functions: \((f \ + \ g)(x)\) and \((f \ - \ g)(x)\).
When a function has polynomials, combine the like terms to add or subtract functions.
When evaluating new functions, you should substitute the input value to find the function's value.

What is a Function Notation

When evaluating function notations for a specific input value, substitute the input value into the algebraic expression that defines the function. When figuring out the value of a function notation, the focus is on one input and the output that goes with it.
