Functions, Relations, and transformations

It is assumed that the reader has studied relations and functions at a more junior level; the further study of these two fundamental concepts is the dominant theme of this volume.
Throughout the book, supplementary sections and also paragraphs or brief notes supplementary in nature have been included where necessary for mathematical completeness. At the end of each exercise, harder questions or those dealing with supplementary material are numbered in red. Each chapter concludes with a concise summary of the material covered, followed by a review exercise.
