What is f(x)= 1 x called?
What is f(x)= 1 x called? The reciprocal function, the function f(x) that maps x to 1/x, is one of the simplest examples of a function which is its own inverse (an involution). The reciprocal function, y = 1/x. For every non-zero x coordinate, the corresponding y coordinate on the graph represents its multiplicative inverse. […]
