Step-by-step explanation:

Key formulas used:

Given ,

We can use the first formula on the left side of the equation.

In this case, for , , we have:

Similarly, we can use the second formula on the right side of the equation.

In this case, for , , we have:

Therefore, when you square both sides of the equation, you get:

*Important:

This answer choice is actually only correct if , because of the first formula we used. If (negative), then . Graphically, you can show this since the line is not equal to but instead . and only overlap if you restrict the domain to (positive numbers), hence only for .
