(B)
if f(a) = K, then that means f sends (a) to (K). 
the inverse function, f-1, goes back where you started, so f-1 sends (K) to (a). 
f-1(K) = a.

Answer:

If ƒ  a. = K, then which of the following must be true?

A) ƒ( K ) = a

B) ƒ -1( K ) = a

C) ƒ -1( a ) = K

Step-by-step explanation:

If ƒ (a) = K, when doing the inverse function we have that: ƒ - 1 (K) = a; changing the site values as the second inverse function of the first.

The answer is: B) ƒ -1 (K) = a
