The answer is C because if you turned Figure Q 90 degrees clockwise, it matches Q', thus a counterclockwise rotation of 270 degrees around the origin had to have been applied.

A is disqualified because if it had been rotated 90 degrees counterclockwise, it would be in the top left quadrant.

B is disqualified because if it was rotated 180 degrees about the origin, it would be in the bottom left quadrant.

D is disqualified because if rotated 270 degrees about the origin it would be in the top left quadrant, same as answer A.

Answer:

Step-by-step explanation:

By counting the height ( frequency ) of each block and adding gives the number of students in total

20 - 24 → 5

24 - 28 → 6

28 - 32 → 5

32 - 36 → 2

36 - 40 → 7

Total = 5 + 6 + 5 + 2 + 7 = 25

Given the recursive formula, each terms is five time the previous one.

This means that:

$f(6)$ is 5 times $f(5)$ , which means $f(6)=5f(5)$
in turn, $f(5)$ is 5 times $f(4)$ , so we have $f(5)=5f(4)$ . This means that $f(6)=5f(5)=5\cdot 5f(4) = 25f(4)$
Finally, $f(4)=5f(3)$ So, substituting this back gives
