Answer:
1st graph - Odd Function
2nd graph - Neither odd nor even function
3rd graph - Even Function
Step-by-step explanation:
We know that,
Even functions are the functions whose graphs are symmetric with respect to y-axis.
Odd functions are the functions whose graphs are symmetric with respect to the origin.
From the options, we have that,
1st graph is symmetric about the origin and is the graph of the line [tex]f(x)=x[/tex].
So, [tex]f(-x)=-x=-f(x)[/tex]
The first graph is the graph of an odd function.
2nd graph can be seen that is neither symmetric about the y-axis nor the origin.
The second graph is neither and odd function nor an even function.
3rd graph is symmetric about the line of the form [tex]y=c[/tex], where 'c' is some constant.
The third graph is the graph of an even function.
