Answer:
Step-by-step explanation:
Given that Z the set of integers is the universal set and
A is given in set builder form.
To convert this into roster form, we can find solutions for x
When
i.e. all integers lying between -2.236 and 2.236
The only integers satisfying this conditions are
-2,-1,0,1,2
Hence A in roster form is
A=
The answer is the first option: Even.
The explanation for this exercise is shown below:
1. By definition, if 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.
