On the complex plane, the number is mapped onto the point with coordinates
.
In other words, the x coordinate is the real part of the number, while the y coordinate is the complex part of the number.
Viceversa, if you start from a point , you can identify the number
.
So, the endpoints of the diagonal are the points and
. These are points A and C in the attached figure.
This means that points B and D have coordinates
So, the correspondant complex numbers are
Answer: y≤0
Step-by-step explanation:
Looking at the question, I'm assuming the equation is .
To find the range if this equation, it would be best to know that the graph of a square root looks like. Knowing that x=-5, the graph starts at -5 and then increases slowly to the right. Since there are no restrictions to this equation, the graph goes towards infinity.
