Question

The domain of the function f = {(1, 3), (3, 5), (2, 6)} is

Answer 1

Answer:

FUNCTION f={(1,3),(3,5),(2,6)}

DOMAIN ={1,3,2}

Answer 2

SOLUTION

TO DETERMINE

The domain of the function f = {(1, 3), (3, 5), (2, 6)}

EVALUATION

We know that for two given sets A and B the Cartesian product of A and B is denoted by A × B and defined as

$\sf{A \times B = \{(x, y) : x \in A \: \: and \: \: y \in B \}}$

Now a Relation R from A to B is a Subset of A × B

Also for two non empty sets A and B a mapping or function f from A to B is a rule that assigns to each element x of A a definite element y in B

Now the given function is

f = {(1, 3), (3, 5), (2, 6)}

Domain of the function

= { x : (x, y) ∈ f }

= { 1 , 2 , 3 }
