The answer is the first option: Even.
The explanation for this exercise is shown below:
1. By definition, if [tex]f(x)=f(-x)[/tex] the fucntion is even.
2. When the graph is symmetric with respect to the y-axis, it is an even function.
3. As you you can see in the graph attached in the problem, the graph is symmetric about the y-axis. Therefore, you can conclude it is an even function.
