For clarity and easiness of expression, this solution is handwritten and attached as a file. Check the complete solution in the attached file.
We are given the functions 
and 
.
let's consider some pairs in the graph of both functions.
in we have (-2, 4), (2, 4), (3, 9), (-5, 25)
in
we have (-2, -4), (2, -4), (3, -9), (-5, -25)
so for the same values of x, we have y's of equal value, but different sign.
This means that the functions are the reflections of each other with respect to the x-axis.
Answer: C <span>reflection over the x-axis</span>
