Your description of $f^{-1}(f(x))$ is a bit muddled, even though the reasoning is correct. It should be, $\{x' \in X \text{ such that } f(x') = f(x)\}$. That's the definition of $f^{-1}(a)$, where I …

We’d need to have 1 = f1 = ar and 1 = f2 = ar2. But by the de nining property of r, we have 1 = f2 = ar2 = a(r +1) = ar +a. Thus we have 1 = ar 1 = ar +a which cannot be satisfed by any value of a. But there’s one more trick we can still deploy. x2 = x+1 is a quadratic equation, and it has two solutions: r = 1+ p 5 2 and ...
WebDetermine composite and inverse functions for trigonometric, logarithmic, exponential or algebraic functions as part of Bitesize Higher Maths WebProof by induction is a way of proving that a certain statement is true for every positive integer \(n\). Proof by induction has four steps: Prove the base case: this means proving that the statement is true for the initial value, normally \(n = 1\) or \(n=0.\); Assume that the statement is true for the value \( n = k.\) This is called the inductive hypothesis.
