Answer:
Correct option: A -> Horizontal or vertical reflection
Explanation:
We can observe that the value of x in f(x) gives a value that is the same value we have in g(x) with the value -x.
That is, x = 1 in f(x) gives the same result as x = -1 in g(x)
So this means that these functions are a reflex of each other in relation to the y-axis, as the x values of one have the same result as (-x) values for the other one.
So the correct option is A: Horizontal or vertical reflection
(It is a horizontal reflection)
