Answer:
<u><em>-29/15</em></u>
Step-by-step explanation:
- <u><em>Multiply 2 and 3 to get 6</em></u>
- <u><em>-6+2/3 + 11/15</em></u>
- <u><em>Add 6 and 2 to get 8</em></u>
- <u><em>-8/3+11/15</em></u>
- <u><em>LCM of 3 and 15 is 15. Convert -8/3 and 11/15 to fractions with 15 as the denominator</em></u>
- <u><em>-40/15 + 11/15</em></u>
- <u><em>Since -40/15 and 11/15 have the same denominator, add them by adding the numerators</em></u>
- <u><em>-40+11 / 15</em></u>
- <u><em>Add -40 snd 11 to get -29</em></u>
- <u><em>-29/15</em></u>
Replace x with 7
10(7) -2(7)
70 - 14
56
f(7) = 56
In this situation, the order matters, since being 1st pick is not the same as being 2nd or 3rd. Therefore, there are 14 choices for the first pick, 13 remaining for the second pick, and 12 for the third pick. This is equivalent to the permutation 12P3.

(If order did not matter, this would use a combination.)
The number is multiplied by 4 down the line so 2,8,32,128,512,2048,8192,32768,131072,524288,2097152
this said, the answer is D
