Web19 okt. 2024 · Here is how the proof seems to look: Suppose that g is not one-to-one. Then we can find distinct x 1, x 2 ∈ X for which g ( x 1) = g ( x 2) = y. But then f ∘ g ( x 1) = f ( … Webthen 2 is a fixed point of f, because f(2) = 2.. Not all functions have fixed points: for example, f(x) = x + 1, has no fixed points, since x is never equal to x + 1 for any real number. In graphical terms, a fixed point x means the point (x, f(x)) is on the line y = x, or in other words the graph of f has a point in common with that line. ...
