Question

For each graph below, state whether it is a function.

Answer 1

As given by the question

There are given that the graph of any function

Now,

To check, whether the given graph is a function or not, use the vertical line test.

Then,

According to vertical line test;

vertical line test is used to define the given curve is function or not.

so,

From graph 1:

Graph 1 represents the function.

From graph 2:

Graph second is not a function

From graph 3:

Graph 3 represents the function.

From graph 4:

Graph 4 also represents the function

Now,

From graph 5:

Graph 5 is not a function.

And,

Graph 6 is not a function.
