(a+b,2b-3)=(4

Which of the following relations are functions from A to B write their domain and range if it is not a function give reason ? f={(a,b),(a,2),(b,3),(b,4)},A={a,b},B={b,2,3,4}

What is (1)/(a-b) -(1)/(a+b) -(2b)/(a^(2)+b^(2))-(4b^(3))/(a^(4)+b^(4)) -(8b^(7))/(a^(8)-b^(8)) equal to ?

Identify the identity function if any. {(a,1),(a,2),(b,3),(b,4)}

Identify the constant function if any. {(a,1),(a,2),(b,3),(b,4)}

If a ne b, b,c satisfy |(a,2b,2c),(3,b,c),(4,a,b)|=0 , then abc =

If a!=6,b,c satisfy |(a,2b,2c),(3,b,c),(4,a,b)|=0 then abc

If a ne 6, b , c satisfy |(a,2b,2c),(3,b,c),(4,a,b)|=0 , then abc =

Let A = [(1,1),(0,1)] and B = [(b_(1),b_(2)),(b_(3),b_(4))] . If 10 A^(10) +Adj (A^(10)) = B then b_(1)+b_(2)+b_(3)+b_(4) is equal to :
