If `A={1,2,3} and B={2,4}`.Let `R={altb}`,then write R in roster form.

If R is the relation "is greater than" from A = {1,2,3,4,5} to B = {1,3,4} , write R as the set of ordered pairs. Also find R^-1 .

Let A = {1,2,3,4} and B = {7,8,9} , then which of the following relations is a mapping or not from set A to set B ? R_2 = {(1,7),(2,7),(3,7),(4,7)}

Let A = {1,2,3,4} and B = {7,8,9} , then which of the following relations is a mapping or not from set A to set B ? R_4 = {(1,7),(2,8),(3,7),(4,8)}

Let A = {1,2,3,4} and B = {7,8,9} , then which of the following relations is a mapping or not from set A to set B ? R_3 = {(1,8),(2,9),(3,8),(4,8)}

Let A = {1,2,3,4} and B = {7,8,9} , then which of the following relations is a mapping or not from set A to set B ? R_1 ={(1,7),(2,8),(1,8),(4,9)}

Let A={1,2,3,5} and B={4,6,9} let R =R={(x,y):abs(x-y) is odd x in A,y in B} write R in the roster form

Let A = {a, b, c} and B ={1, 2, 3} be two sets. State with reasons which of the following is a relation form A to B: R={(a, 2),(a, 3),(b, 1),(c, 3),(b, 2)}

Let A={1,3,5,7} and B={p,q,r} .Let R be a relation define by R={(1,p),(3,r),(5,q),(7,p),(7,q)} , find the domain and range of R .

Let A = {1, 2, 3, 4, 6} . Let R be the relation on A defined by {(a , b): a , b in A , b is exactly divisible by a}.(i) Write R in roster form(ii) Find the domain of R(iii) Find the range of R.

A={1,2,3,5}and B={4,6,9} . A relation R is defined from A to B by R={(x,y): the difference between x and y is odd}. Write R in Roster form.
