Since this is a permutation, it would be 5!(factorial)
so 5x4x3x2x1

Answer:
C 18(2 + 3)
Step-by-step explanation:
The GCD of 36 and 54 is their difference, 18. Factoring that out of the sum, you have ...
36 + 54 = (18·2 + 18·3) = 18(2 + 3) . . . . matches choice C
The answer is B,
.
Here's analyses of the other options:
Option A. You can clearly see that

is not defined for

, so the function

doesn't have the same domain as that of

, hence can't be the answer.
Option C. By the definition of absolute value, we know that

, this is the same function, hence not the answer.
Option D. This is just

shifted one unit to the right, not flipped.
