The correct answer for the problem shown in the figure atttached is the last option (option D), which is shown below:
D.(-x-9i)(x-9i)
If you want to verify that the option D.(-x-9i)(x-9i) is the correct answer, you can apply the distributive property to (-x-9i)(x-9i).
Therefore, when you apply the distributive property, you obtain that the result is:
-x²-81
The graph attached shown this equation, which is a parabola.
