Find f - -1 ( x ). f ( x ) = x $-$ 3 A) f ^{- -1}( x ) = x B) f ^{- -1}( x ) = x + 3 C) f - -1 ( x ) = x $-$ 3

Question

Quizplus · Accepted Answer

To find f - -1 (x), we need to replace every instance of x in f(x) with -1. f(x) = x - 3 Replacing x with -1, we get: f(-1) = (-1) -3 = -4 Therefore, f - -1 (x) = -4 The only choice that gives us this result is B, where f ^{- -1}( x ) = x + 3. Note that choice A is incorrect because f ^{- -1}( x ) = x is simply the original function f(x), and we are looking for f - -1 (x). Choice C is also incorrect as it gives us the original function f(x) rather than f - -1 (x).
