Computer graphics frequently use reflections. Reflections can speed up the generation of a picture or create a figure that appears perfectly symmetrical.

(a) For the given f(x), constant k, and viewing rectangle, graph x = k, y = f(x), and y = f(2k - x). 

(b) Generalize how the graph of y = f(2k- x) compares to the graph of y = f(x).

f(x) = x - 2x + 1, k = -6, [-15, 3, 1] 6, [15, by [-3,9,1]
