Which correctly models selecting a permutation without repetition of 8 objects taken 3 at a time?

A. 8P3 = 8!/5!

B. 8P3 = 8!/3!

C. 3P8 = 3!/8!

D. 3P8 = 5!/8!

The first step here is to define what a function is, right? So here's the definition:

A function is an equation that has only one answer for y for every x

Because of this, we now rule out "C" and "D" as correct answers right of the bat. Actually if you are experienced enough to know, you will realize that "B" is also eliminated right away as well because it deals with {(Absolute Value)}.
