Question

Q 14 domain and range and R is a function

Answer 1

for example if you take a question

A= 1,2,4

B=5,3

if they ask you the function from A to B

you will write as F= { (1,5) , (1,3) , (2,5) , (2,3) , (4,5) , (4,3) }

domain is the first number containing in the 'F'

Range is the second number of each element.

so here, the domain is A i.e., 1,2,4 & the range is B i.e., 5,3
