ie, y is the image of x by f –1 iff x is the image of y by f, or f –1 maps x to y iff f maps y to x.We say that a function is invertible if it has its inverse function, ie, if its inverse relation is also a function. We've seen that if a function is one-to...
Theorem 5.6 Reflective property of inverse functions The graph of f contains the point (a, b) if and only if the graph of f^-1 contains the point (b, a). Existence of an Inverse Function. Not every function has an inverse function, and Theorem 5.6 suggests a graphical test for those...
[Definition 10.2.1] Let f:X\rightarrow \mathbb{R} be a function, and let x_0\in X。 We say that f attains a local maximum at x_0 if and only if there exists a \delta>0 such that the restriction f|X\cap(x_0-\delta,x_0+\delta) of X\cap (x_0-\delta,x_0+\delta) at...
