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. ... Web22 mrt. 2024 · Ex 1.2, 1 Show that the function f: R* → R* defined by f(x) = 1/x is one-one and onto, where R* is the set of all non-zero real numbers. Is the result true, if the domain R* is replaced by N with co-domain being same as R*?

The horizontal line test may be used. * If (a,b) is on f(x),then (b,a) is on f -1(x). * - f(f 1(x)) = f -(f(x)) = x * The domain of f(x) becomes the range of f -1(x) * The range of f(x) becomes the domain of f -1(x) ... five minute christmas craft
