Answer:
-6±3i√2
Step-by-step explanation:
First we need to simplify the radical here which is √-288. We can make this i√288, and then further simplify by taking out 12 giving us 12i√2. Now we have
-24±12i√2/4
From here we just divide all the terms in the numerator by 4 and get -6±3i√2
I think I know what you are thinking and you are halfway on the right track. : ) You are probably looking at the x-axis right in between the pentagon and its reflection. This <em />is the right line, but it is a y-line and not x. When we say a line is at x = 0, we mean that every point on that line has an x-value of 0, such as (0,1), (0,2), (0, 3) etc. Any line in the form x = 0 (or any other number) is a vertical line. Y-lines are the same way but they run horizontal like the line of reflection in this problem. : )
D would be your answer. Since the x is negative the graph is decreasing and -3 is you y-intercept
