![]() ![]() ( x, y ) → ( x + a, y + b ) īecause addition of vectors is commutative, multiplication of translation matrices is therefore also commutative (unlike multiplication of arbitrary matrices). When addressing translations on the Cartesian plane it is natural to introduce translations in this type of notation: If function transformation was talked about in terms of geometric transformations it may be clearer why functions translate horizontally the way they do. A graph is translated k units horizontally by moving each point on the graph k units horizontally.įor the base function f( x) and a constant k, the function given by g( x) = f( x − k), can be sketched f( x) shifted k units horizontally. In function graphing, a horizontal translation is a transformation which results in a graph that is equivalent to shifting the base graph left or right in the direction of the x-axis. For instance, the antiderivatives of a function all differ from each other by a constant of integration and are therefore vertical translates of each other. For this reason the function f( x) + c is sometimes called a vertical translate of f( x). If f is any function of x, then the graph of the function f( x) + c (whose values are given by adding a constant c to the values of f) may be obtained by a vertical translation of the graph of f( x) by distance c. Often, vertical translations are considered for the graph of a function. ![]() All graphs are vertical translations of each other. ![]() The graphs of different antiderivatives, F n( x) = x 3 − 2x + c, of the function f( x) = 3 x 2 − 2. In geometry, a vertical translation (also known as vertical shift) is a translation of a geometric object in a direction parallel to the vertical axis of the Cartesian coordinate system. For the concept in physics, see Vertical separation. ![]()
