right function notation


We are said to be using if we write functions to the right of their arguments. That is, if α:X→Y is a function and x∈X, then x⁢α is the image of x under α.

Furthermore, if we have a function β:Y→Z, then we write the compositionMathworldPlanetmath of the two functions as α⁢β:X→Z, and the image of x under the composition as x⁢α⁢β=x⁢(α⁢β)=(x⁢α)⁢β.

Compare this to left function notation.
