![]() Note: there are no method marks awarded for any transformation questions no matter how many marks are being awarded, they are all answer marks.ĭilation from the x-axis by a factor of aĭilation from the y-axis by a factor of aĮxample 3. The transformation y af(x) is a vertical stretch of y f(x) with scale factor a parallel to the y-axis and then a reflection in the x-axis. The graph of y f (-x) is a reflection in the y axis. In methods we are generally concerned with - reflections in the x-axis, y-axis and line y=x Reflections simply flip the graph relative to a certain line. All dilation factors are positive.Ī dilation from the y-axis by a factor larger than one ( > 1) will result in the graph being stretched away from the y-axis.Ī dilation from the y-axis by a factor less than one ( 1) will result in the graph being stretched away from the x-axis.Ī dilation from the x-axis by a factor less than one ( < 1) will result in the graph being compressed towards the x-axis. Translations are when we shift the entire graph left, right, up or down.ĭilations stretch or compress the graph. A vertical reflection reflects a graph vertically across the x-axis, while a horizontal reflection reflects a graph horizontally across the y-axis. Graph functions using compressions and stretches. You should have seen some graph transformations before, such as translations and reflections recall that reflections in the x-axis flip f(x) vertically. Another transformation that can be applied to a function is a reflection over the x- or y-axis. Determine whether a function is even, odd, or neither from its graph. Which of the following describes the transformation of the graph y x2 in graphing y -x2 - 5 reflect over the x-axis and shift down 5 reflect over the y-axis and shift down 5 reflect over the x-axis and shift left 5 See answers Advertisement sqdancefan Let f (x) x². Columbia University.There are three types of transformations which we will be dealing with: translations, dilations and reflections. Graph functions using reflections about the x-axis and the y-axis. “Private tutoring and its impact on students' academic achievement, formal schooling, and educational inequality in Korea.” Unpublished doctoral thesis. Tutors, instructors, experts, educators, and other professionals on the platform are independent contractors, who use their own styles, methods, and materials and create their own lesson plans based upon their experience, professional judgment, and the learners with whom they engage. Reflection about the y-axis Vertical shifting or stretching Horizontal shifting or stretching Tell me if I'm wrong, but I believe that in any function, you have to do the stretching or the shrinking before the shifting.
