Often, vertical translations are considered for the graph of a function. 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". For this reason the function "f"("x") + "c" is sometimes called a vertical translate of "f"("x"). 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.
