WebWe use the symbol f − 1 to denote an inverse function. For example, if f (x) and g (x) are inverses of each other, then we can symbolically represent this statement as: g(x) = f − 1 (x) or f(x) = g −1 (x) One thing to note about the inverse function is that the inverse of a function is not the same as its reciprocal, i.e., f – 1 (x) ≠ ... WebIf true again, then f\left( x \right) and g\left( x \right) are inverses. Success! If false, then f\left( x \right) and g\left( x \right) are not inverses.
