For each graph below, state whether it represents a function

Graph number 3, 4 and 6.

Step-by-step explanation:

First , lets numbering the graph (as given figure) as,  1,     2,      3,

                                                                                        4,     5,      6.

We know that a function is a special type of relation in which every element of the the domain have a unique image in the co-domain . If we check all given graph with the help of vertical line test , then we get the given graph is a function or not.

In vertical line test - if a vertical line (vertical line drown at each point of domain ) passing through the graph cut the graph at exactly one point, then the relation is a function.

Now we test and observe the graph with the help of vertical line test, we gate the graph number  3, 4 and 6 are the function because a vertical line passing through the graph , it cuts at only one point (it valid for all point of domain ), and the graph number 1, 2 and 5 are not a function because a vertical  line passing through the graph, it cuts at more than one point (it valid for at list one point of domain)

the answer is b i just did that
