Answer:
Option D. 360°
Step-by-step explanation:
As we can see in the figure attached Its a regular hexagon having center at origin.
We know for a regular hexagon inscribed area can be divided in six equal triangles. Since every triangle is equilateral triangle so all angles at the center should be 60°.
If we rotate (-2, 4) by 60° the point (-2, 4) replaces (2, 4). Now to get this point (-2, 4) back to its original position hexagon should be rotated by six times of 60° (6×60°= 360°).
Therefore, to get identical image of original hexagon it should be rotated by angle k = 360°
Option D 360° is the answer.

Ok:
Step-by-step explanation:
So f°g . means f(g(x)). (The ° should be more center and bigger but I don't know to do that on a keyboard). f(g(x)) means that you replace the x in f(x) with the g(x) function. i.e:
if f(x) = 2x+2
and g(x) =
f(g(x)) = .
Similarly, in this case, we get f(x) = 2x-3 and g(x) = 3x-2.
Then, f(g(x)) or f°g(x) is 2(3x-2) - 3.
And we plug in -2 to solve:
2(3(-2)-2)-3.
and get -19.
Check if I am wrong because everyone makes mistakes but that is the way to solve this.
