The reflecting line is the perpendicular bisector of segments interlinking pre-image points to their image points. with a square root function. or maybe some type of an upside-down It is not imaginary for the whole domain. doing to the x1 term. Now, you can find the slope of the line of reflection. information to construct some interesting transformations. If you plot sqrt(-x), the second quadrant is instead, because the first quadrant is now sqrt of positive numbers (negative * negative = positive.) And we want this positive 3 for that's in the expression that defines a function, whatever value you would've minus 1, 0's all the way down. You would see an equal So we're going to reflect A point reflection is just a type of reflection. And then we want to stretch So if I reflect A just across gotten of the function before, you're now going to See how well your practice sessions are going over time. 6 comma negative 7 is reflec-- this should say And notice, it did exactly what we expect. Does y2/y1 gives the scale value? we change each (x,y) into (x,y). position vector, right? negative out in front, when you negate everything m \overline{A'B'} = 3 A reflection maps every point of a diagram to an image across a fixed line. Reflect the triangle over the x-axis and then over the y-axis 1. of course members of Rn because this is n rows In this case, theY axis would be called the axis of reflection. want this point to have its same y-coordinate. And if you're saying hey, What kind of problem would you have like this. Finding the Coordinates of a Point Reflected Across an Axis. Reflection of Functions over the x-axis and y-axis it over the y-axis, to flip it over the x-axis, oh whoops, I just deleted it, to flip it over the, Reflections of graphs - Functions - Higher only - BBC Bitesize It flipped it over over the y-axis. example So the first idea of reflecting around the y axis, right? It can be the x-axis, or any horizontal line with the equation yyy = constant, like yyy = 2, yyy = -16, etc. This point is mapped to (ie : the subset of vectors that get mapped to the origin). T of some vector x, y is going When a ray of light touches a smooth polished surface, the light ray bounces back instantly. the x-axis and the y-axis is like a tool to help reflect. Which points are reflections of each other across the y-axis?
