Cartesian product , function , relation , graph , and domain, range are discussed in this presentation.

2. Cartesian product
 Set of all order pair of two sets is said to be Cartesian
product.
 Denoted by : A x B, B x A
 The Cartesian product of set A and b is not equal to
the Cartesian product of B and A.

3.  If set A = {5, 6} and B = { 7, 8}.

8.  Graphs are pictures that help us to understand
amounts and locations.
 The are many kinds of graph each having special
parts.

9.  A circle graph is shaped like a circle, some
