you have the wrong equation posted.
if you meant to post
the answer would be b.
first reflected on the axis y=0 (x axis) and then translated by the vector (0,2)
i have attached a screenshot of the graphs : )
the red is y=x²
the blue is y=-(x²-2)
a reflection is well a reflection! the shape will be exactly the same as the one that is being reflected. congruent is just a synonym for same, two figures that are congruent are the exact same.
