15444 ways we can choose 5 objects, without replacement, from 15 distinct objects.
Given that, suppose we want to choose 5 objects, without replacement, from 15 distinct objects.
<h3>What is a permutation?</h3>A permutation is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters.
Now, = 13!/(13-5)!
= 13!/8! = 13x12x11x10x9= 1287 x 120 = 15,444
Therefore, 15444 ways we can choose 5 objects, without replacement, from 15 distinct objects.

Answer: second option
Step-by-step explanation:
To find the inverse function of the given function f(x):
You need to:
Substitute into the function:
Now, you need to solve for "x", to do this, you must divide both sides of the function by 2:
Now, replace "x" with "y" and replace "y" with "x":
Therefore, substituting you get:
