Transformations Write transformations in the following order • Shifts left/right • Shrinks/stretches • Reflections • Up/down Shifts: • • • • f(x + C) f(x - C) f(x)+c f(x)-C Shifts left: horizontal translation left C units Shifts right: horizontal translatio~n right C units Shifts up: vertical translation up C units Shifts down: vertical translation down C units Reflections: • -f(x) reflection in the X-axis (notice the negative is outside the function.) • f( -x) reflection in the V-axis (notice the negative is inside the function) Vertical shrinks/stretches Horizontal shrinks/stretches f(f)k af(x) If a >1 then it is a vertical stretch by a factor of a If b>l then it is a horizontal stretch by a factor of b . If 0 < a < 1 then it is a vertical shrink by a factor of a If 0 < b < 1 then it is a horizontal shrink by a factor of b Describe the transformation on the parent graph [ex) = 1.
