In this question, we are asked to classify students with this age.
00:08
So students has to be classified with is or her age.
00:18
So we have to use this relationship to answer subdivision a and b.
00:24
So we have to say whether is the given relationship is age a function of student.
00:36
So this is what we have to find.
00:40
So we already know that a function is a relation for which each value of domain should be associated with exactly one value of core domain.
01:01
So this is the definition of function.
01:05
So according to this, if we say that, let's say that x is the set of students and y is the 8 .5.
01:16
Age of students.
01:22
So we know that each students as a age which is unique or it can be more than one.
01:30
Suppose let's say we have a and b as a student.
01:35
So if a's age is 14 it is possible for b's age should also be a 14 one.
01:41
So from this we can say that every element of domain as exactly one core domain...
