When there is a negative in squre root, it means imaginary number come in. 'i' is usually the varible used to identify imaginary numbers.
First remove the negative from the square root and find the square root of 4, which is 2. Then add i to 2. 2i
Now solve for the positive then negative.
-2 + 2i
----------- = -1 + 1i
2
-2 - 2i
----------- = -1 - 1i
2
Both -1 + 1i and -1 - 1i are the answers.

Answer:
A and D should be correct
Step-by-step explanation:
The x coordinate of point A that is shown on the graph is 3π/16.
<h3>How to explain the graph?</h3>
From the information given, y = kcos(8x). Also, the axis of symmetry is given as kx.
Therefore, the x coordinate will be:
= π/8 + π/16
The LCM of 8 as 16 is 16.
= 2π/16 + π/16
= 3π/16
