Determine whether the function in the graph is even or odd

The correct option is:
The function is even because it is symmetric with respect to the y-axis
The function is even if its graph is symmetric with respect to the y-axis
and it is odd if its graph is symmetric with respect to the origin.
Clearly as we can see from the graph that the function is symmetric with respect to the y-axis
Hence, the given function is an even function.
So, the correct option is:
The function is even because it is symmetric with respect to the y-axis
