Answer:
1680
Step-by-step explanation:
Since there are 4 places (frames) to put up each poster, we think individually:
In the first place they can place ANY OF THE 8 POSTERS
In 2nd place, they can place ANY OF THE REMAINING 7 POSTERS
In 3rd place, they can place ANY OF THE REMAINING 6 posters
and
in last place, they can place ANY OF THE REMAINING 5 posters
The number of ways is the multiplication of them all, so:
8 * 7 * 6 * 5 ways = 1680 ways
I hope this helps you

Option B:
f(3) = 5
Solution:
Given function:
- If x value is less than –2, that is –3, –4, –5, –6, ... then f(x) = –x².
- If x value is greater than or equal to –2 and less than 0, that is –2 and –1 then f(x) = 3.
- If x value is greater than or equal to 0, that is 0, 1, 2, 3,... then f(x) = x +2.
<u>To find the value of f(3):</u>
Here x value is 3 which is greater than 0 (3 > 0).
Therefore, f(x) = x + 2.
Substitute x = 3 in the above function.
f(3) = 3 + 2
f(3) = 5
Hence option B is the correct answer.
