This document is a module for a general mathematics course focusing on the composition of functions. It outlines the expected learning outcomes, including defining and identifying operations on functions, as well as performing addition, subtraction, multiplication, division, and composition. The module refers to composition of functions as 'function of functions'.

1. General Mathematics
Quarter 1 – Module 3b:
Composition of
Functions

2. After going through this
module, you are expected to:
1. define operations on functions;
2. identify the different operations on
functions; and
3. perform addition, subtraction,
multiplication, division, and
composition of functions.

3. • Some authors
call this
operation as
“function of
functions”.
