For the basic function f(x) = x, the transformed function y = f(x) + D shows a ​ (a)   translation of the function. For D > 0, the resulting graph shifts ​ (b)   . For D < 0, the resulting graph shifts ​ (c)   . The basic function and the resulting graph are parallel because they have the same ​ (d)   but different ​ (e)   .
