• Define relation
• Hello sir, Please explain this sum, Let R be the relation defined on the set N of natural numbers as, R={ (x,y),x divides y: x,y € N}. Then the values are?  
• what is the exact difference between co domain and range
• Solve 6th sum nd plz tell how is any mapping done.like what is the rule for this mapping

• Define relation.
• Let A = {2, 4, 6} and B = {6, 8, 12, 18}. Define a relation R from A to B by R= {(x, y): x divides y; x A, y B}. Express R as a set of ordered pairs.
• Determine the domain and range of the relation R defined by R = {(x + 2, x + 4): x  {0, 1, 2, 3, 4}
• If R is the relation ‘is less than’ from A = {2, 4, 6, 8, 10} and B = {2, 6, 10}, write down the Cartesian product corresponding to R.
