WebLet $f(a) = x^3 + 2x + 3$. IF $f(a) = f(b)$, you want to show that $a = b $. You can show this by contradiction. In fact, if $a \neq b$. Then, either $a > b$ or $a < b$. WebSimilarly, for all y in the domain of f^(-1), f(f^(-1)(y)) = y; Can you always find the inverse of a function? Not every function has an inverse. A function can only have an inverse if it is one-to-one so that no two elements in the domain are matched to the same element in the range. A non-one-to-one function is not invertible.
