Nonrigid Transformations :
\A nonrigid transformation of the graph of y = f(x) is represented by g(x) = c f(x), where the transformation is a vertical stretch if c > 1 and a vertical shrink if 0 < c < 1.
\Another nonrigid transformation of the graph of y = f(x) is represented by h(x) = f (cx), where the transformation is a horizontal shrink if c > 1 and a horizontal stretch if 0 < c < 1.
\The parent function is f(x) = x2, and the transformation function is g(x) = (9x)2.
\The graph of g(x) = (9x)2 is a horizontal shrink or compression ( since c = 9 > 1) of the graph of f(x) = x2 because
\g(x) = (9x)2
\= f (9x).
