I did develop the formula using the 3 steps shown in the graphic I describe them bellowAgain, Fig 1 is y = f(x) Its reflection about the xaxis is y = −f(x) Every yvalue is the negative of the original f(x) Fig 3 is the reflection of Fig 1 about the yaxis Every point that was to the right of the origin gets reflected to the left And every point that was onVertical reflection can be defined as the reflection which is along the X coordinate axis and all the values of y coordinate axis are flipped to other part vertically without making any changes in the values of x coordinate axis If f (x) is a function then its vertical reflection can be represented as y=f (x)

Key Points A vertical reflection is given by the equation y=−f(x) y = − f ( x ) and results in the curve being "reflected" across the xaxisAnswers A1 The transformation is the reflection in the vertical line with equation (normalsize {x=1}) This is reflection in the line (normalsize {y=x}), which passes through the origin (normalsize { 0,0}) and the point (normalsize { 1,1}) A3The line y = x is the point ( y, x ) Reflect over any line Remember that each point of a reflected image is the same distance from the line of reflection as the corresponding point of the original figure The line of reflection will lie directly in the middle between the original figure and its image

Rule Let y = f (x) be a function In the above function, if we want to do reflection through the yaxis, x has to be replaced by x and we get the new function y = f (x) The graph of y = f (x) can be obtained by reflecting the graph of y = f (x) through the yY = f (x) y = f (−x) Remember, the only step we have to do before plotting the f (x) reflection is simply divide the xcoordinates of easytodetermine points on our graph above by (1) When we say "easytodetermine points" what this refers to is just points for which you know the xSo, reflection in X axis means reflection in the line y = 0 Let P (x, y) be any point in the plane Draw a perpendicular PL from the point P to the X axis and produce it to the point P' such that PL = LP' Then P' is the image of P after reflection in X axis Here, coordinates of L are (x, 0)

We have reflected the shape in the line y = −x A Formula to Reflect a Point in y = −x Using Cartesian Coordinates In general, we write Cartesian coordinates as x is the xcoordinate y is the ycoordinate x and y can taken any number The reflected point has Cartesian coordinates The rule for reflecting over the Y axis is to negate the value of the xcoordinate of each point, but leave the value the same For example, when point P with coordinates (5,4) is reflecting across the Y axis and mapped onto point P', the coordinates of P' are (5,4)What is the formula for reflection Y = X?

Answer (1 of 3) Hey Fam One of the most basic transformations you can make with simple functions is to reflect it across the yaxis or another vertical axis In a potential test question, this can be phrased in many different ways, so make sure you recognize the following terms as just anotherX y z In other words, The Tangential Electric Field is Continuous So E i (y= 0) E r (y= 0) = E t (y= 0) The component of the Efield that lies in the xz plane is continuous as you move across the plane of the interface Here, all Efields are in the zdirection, which is in the plane of the interface (We're not explicitly writing Reflection Over the XAxis For our first example let's stick to the very simple parent graph of y = x^2 {See video for graph} On the screen you can see that the graph of this equation is a parabola
