Question

2. For the given function F= { (1, 3), (2, 5), (4, 7), (5, 9), (3, 1) }, write the domain and
range.

Answer 1

Hi,

*****************************************************
f : A -> B is a function from A to B then

A is called domain (set of first coordinates of

each ordered pair )

B is called range (set of second coordinates of

each ordered pair )
***************************************************

According to the problem given ,

f = { ( 1, 3 ) , ( 2 , 5 ) , ( 4 , 7 ) , ( 5 , 9 ), ( 3 , 1 )}

domain of f = set of first coordinates }

= { 1 , 2 ,3 , 4 , 5 }

Range = set of second coordinates of each

ordered pair

= { 1 , 3 , 5 , 7 , 9 }

I hope this helps you.
