Answer:
--------------------
The function y = x² - 5 is the translation of the parent function y = x² down by 5 units.
Since the parent function is y = x², it is a parabola that has its vertex at the origin and opens up as its coefficient is positive.
Looking at the answer choices, we see option A is the correct one.
Other options are incorrect:
- Option B is reflection of parent function in the x-axis,
- Option C is translated down,
- Option D is translated to the right.
