Decide whether it is an even function, an odd function, or neither

Given:
There are 2 graphs and 2 functions given in the question
Required:
We need to identify that which are even and which are odd
Explanation:
Even function:
f(-x) = f(x)
The graph of an even function is symmetric with respect to the y-axis.
Odd function:
f(-x) = -f(x)
The graph of an odd function is symmetric with respect to the origin
Here 1st graph is neither even nor odd function because it is not symmetric with respect to the y-axis and also not symmetric with respect to the origin
2nd graph is even because it is
1st function is neither even nor odd because
[tex]f(-x)=-6(-x)^5+7x^2=6x^5+7x^2\ne-f(x)[/tex]2nd function is
