- Two functions, f(x) and g(x), are combined in similar ways to addition, subtraction, multiplication, and division of real numbers. This allows the formation of new functions.
- The document demonstrates examples of combining f(x)=x+1 and g(x)=2x using addition, subtraction, multiplication, and division. It shows the algebraic steps to derive each new function h(x) and evaluates h(x) for various x values.
- Graphs of the functions h(x) are provided to illustrate the relationships between the combined functions.
