This chapter contains three topics, which although closely related, could be studied separately. Mappings and mapping diagrams (Sections 14.1 and 14.2) and the composition of functions (Section 14.3) are required by only a few Examining Boards. Function notation and the ability to evaluate functions for given values of the variable (Section 14.4) are used later in the book, while a knowledge of variation (Section 14.5) is essential in engineering and science, and is required by most Boards.
