Question

Given F = {(2, 6), (3, 1), (4, 5), and (5, 3)}, Find F^-1(3).

A) 2
B) 1
C) 4
D) 5

Answer 1

The value of F ^ -1 (3) is 5. Option D is answer.

Step-by-step explanation:

Given Set: F = {(2, 6), (3, 1), (4, 5), (5, 3)}

Inverse Function Definition: F-inverse of y equals x if F of x equals y

Finding F-inverse of 3:

Start with the definition of the inverse function: F-inverse of 3 means finding an x such that F of x equals 3.

Look through the set F to find the pair where the second element is 3. In this case, it's (5, 3).

So, F-inverse of 3 equals 5, indicating that applying the inverse function to 3 gives us 5.

Therefore, the correct answer is option D) 5.
