So, 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) 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 parabolaY = 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 x

A reflection maps every point of a figure to an image across a fixed line The fixed line is called the line of reflection What is the equation for reflection?Given a function f ( x) \displaystyle f\left (x\right) f (x), a new function g ( x) = f ( − x) \displaystyle g\left (x\right)=f\left (x\right) g(x) = f (−x) is a horizontal reflection of the function f ( x) \displaystyle f\left (x\right) f (x), sometimes called a reflection about the y axis 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)
Graphing Reflections In addition to shifting, compressing, and stretching a graph, we can also reflect it about the xaxis or the yaxisWhen we multiply the parent function latexf\left(x\right)={b}^{x}/latex by –1, we get a reflection about the xaxisWhen we multiply the input by –1, we get a reflection about the yaxisFor example, if we begin by graphing the parentAnswer (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 anotherWe 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
X 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 writingReflection in the line y=−x The rule for a reflection in the origin is (x,y)→(−y,−x) How do you reflect an equation over the y axis? 👉 Learn how to reflect points and a figure over a line of symmetry Sometimes the line of symmetry will be a random line or it can be represented by the x
I was trying to understand how to calculate the reflection vector and found these answers I couldn't understand them easily, so I took my time to do it myself, the good thing is that I can now detail it in an ELI5 fashion!Answers 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}) A3Quadrant 1 (,) Quadrant 2 ( , ) Quadrant 3 (, ) Quadrant 4 (, ) 90 degree rotation 1)flip order of x and y

Use the slopeintercept form to find the slope and yintercept Tap for more steps The slopeintercept form is y = m x b y = m x b, where m m is the slope and b b is the yintercept y = m x b y = m x b Find the values of m m and b b using the form y = m x b y = m x b m = − 1 m = 1 b = 0 b = 0(x, y) → (x 5, y 3) y = 2x 4 → (y 3) = 2(x 5) 4 y 3 = 2x 10 4 y 3 = 2x 6 y = 2x 3A point reflection is just a type of reflection In standard reflections, we reflect over a line, like the yaxis or the xaxisFor a point reflection, we actually reflect over a specific point, usually that point is the origin $ \text{Formula} \\ r_{(origin)} \\ (a,b) \rightarrow ( \red a , \red b) $
What is the formula for reflection Y = X?The line y=x, when graphed on a graphing calculator, would appear as a straight line cutting through the origin with a slope of 1 When reflecting coordinate points of the preimage over the line, the following notation can be used to determine the coordinate points of the image r y=x = (y,x) For example For triangle ABC with coordinate points A (3,3), B (2,1), and C (6,2), apply a reflection5x6=3x8 \frac {3} {4}x\frac {5} {6}=5x\frac {125} {3} \sqrt {2}x\sqrt {3}=\sqrt {5} 7y53y1=2y2 \frac {x} {3}\frac {x} {2}=10 linearequationcalculator y=x

To flip or reflect (horizontally) about the vertical yaxis, replace y = f(x) with y = f(x)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 yThe 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
Make y the subject of the formula 2y = x 1, so y = ½(x 1) Note that the graph of f1 will be the reflection of f in the line y = x This video explains more about the inverse of a function Graphs Functions can be graphed A function is continuous if its graph has no breaks in it An example of a discontinuous graph is y = 1/x, sinceA reflection is a transformation representing a flip of a figure Figures may be reflected in a point, a line, or a plane When reflecting a figure in a line or in a point, the image is congruent to the preimage A reflection maps every point of a figure to an image across a line of symmetry using a reflection matrixAgain, 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 on
