Relations and Functions G11
Much of mathematics is about finding a pattern – a recognisable link between quantities that change. In our daily lives, we often come across patterns that characterise relations such as mother and daughter, brother and sister, father and son, teacher and student, and so on. In mathematics as well, there are relations between numbers that can be represented using certain signs and symbols. In this chapter, we will learn about relations, cartesian products, application of sets in relations, functions and their types, algebra of functions, and graphs. This will help you capture the idea of a precise correspondence between quantities in mathematics.
