Which complex number does not fall within the shaded region in this graph?
-2i
2 − i
-2 + 3i
1 − i
-2 − 3i

2-i does not fall within the shaded region.

B is correct

Step-by-step explanation:

We are given a graph on complex plane. We need to choose the points which are not within shaded region.

We will plot each point and then see which are outside the shaded region.

Please see the attachment for plotting point.

I Point:  -2i, In coordinate form (0,-2)

II Point: 2-i, In coordinate form (2,-1)

III Point: -2+3i, In coordinate form (-2,3)

IV Point: 1-i, In coordinate form (1,-1)

V Point: -2-3i, In coordinate form (-2,-3)

Now, we will plot the points on graph and check position.

In graph we can see (2,-1) lie outside the shaded area.

Hence, 2-i does not fall within the shaded region.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
