(2,1),(5,5),(-6,7)

In the following which is a function ? (i) {(1,2),(2,3),(3,4),(4,5),(5,6),(6,7)}

Which of the following relations are functions? Give reason. If it is a function, determine its domain and range. (i) R= {(2,1), (3,1), (4,2), (5,7), (6,9)} (i) R = {(2,2), (2,4),(3,3),(4,4),(5,8)} (iii) R={(1,3),(1,5),(2,5),(3,6),(3,7)}

Let A={1,2,3,4},B={5,6,7} and f={( 1,6),(2,7),(3,5),(4,6)} . The f is :

Let A={1,2,3},B={5,6,7} and f:A to B be a function defined as f={(1,6),(2,5),(3,7)} Then f is :

Compute : 2{:[(2,3,4,1),(-5,11,6,7)]:}+5{:[(11,13,-3,4),(5,-3,4,-7)]:}-6{:[(6,12,4,-2),(-3,5,11,7)]:} .

Show that A=[(1,5,6),(5,2,7),(6,7,3)] is a symmetric matrix as A^T =A .

If A = {:[(1,5),(6,7)] , then find A + A'

Let A = {1,2,3}, B {5,7,6} and f : A to B be defined as f = {(1,7), (2,6),(3,5)}. Then f is :
