Answer:
a) the function is even because it is symmetric with respect to the y-axis.
Step-by-step explanation:
An even function means that each y-value of a function is the same for both a positive and negative x-value. This. can be seen by the coordinate points (-1,-5) and (1,-5). This relationship can be modeled by f(x) = f(-x) which is true for all functions with the highest degree being even. This also means that the function is symmetric with respect to the y-axis since the function shape is just mirrored.
Therefore, the correct answer choice is a).
