Reflection over x and y axis equation
Reflection over x and y axis equation-When we multiply the parent function f (x) = bx f (x) = b x by –1, we get a reflection about the x axis When we multiply the input by –1, we get a reflection about the y axis For example, if we begin by graphing the parent function f (x) = 2x f (x) = 2 The rule for reflecting over the X axis is to negate the value of the ycoordinate of each point, but leave the xvalue the same For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,4)

Reflection in the x axis A reflection of a point over the x axis is shown The rule for a reflection over the x axis is ( x , y ) → ( x , − y ) Reflection in the y axis A reflection of a point over the y axisA function f f is called an even function if f(x)= f(−x) f ( x) = f ( − x) for all x x in the domain of f f In other words, a function is even if performing a reflection about the y y axis does not change the graph of the function To help remember the definition of an even function, notice that the example of an even function we gaveThe equation of the line of symmetry To describe a reflection on a grid, the equation of the mirror line is needed Example Reflect the shape in the line \(x = 1\) The line \(x = 1\) is a
Reflections Lesson covers reflections over four quadrants Learners initially identify the equation of the vertical and horizontal lines Learners then identify how to reflect a shape in the x or y axis Lesson is consolidated with a plenary which can take place using miniwhiteboards or as a discussion The lesson doesn't cover y = xApply the rule to find the vertices of the image Since there is a reflection across the xaxis, we have to multiply each ycoordinate by 1 That is, (x, y) > (x, y) Step 2Reflections in Math Applet Interactive Reflections in Math Explorer Demonstration of how to reflect a point, line or triangle over the xaxis, yaxis, or any line x axis y axis y = x y = x Equation Point Segment Triangle Rectangle y =
Reflection over the line y = − x A reflection in the line y = x can be seen in the picture below in which A is reflected to its image A' The general rule for a reflection in the y = − x (A, B) → (− B, − A)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 yaxis The notation or rule for a reflection over the yaxis is (x, y) → (x, y)

Dilations make the graph wider or thinner Reflections flip the graph like a mirror In the standard form absolute value equation, y=axhk, hPurplemath The last two easy transformations involve flipping functions upside down (flipping them around the xaxis), and mirroring them in the yaxis The first, flipping upside down, is found by taking the negative of the original function;The equation of the line of the mirror line To describe a reflection on a grid, the equation of the mirror line is needed Example Reflect the shape in the line \(x = 1\) The line \(x = 1

The answer from question (1) is reflected in the line x = 4 What is the equation of the image?Another transformation that can be applied to a function is a reflection over the latexx/latex– or latexy/latexaxis A vertical reflection reflects a graph vertically across the latexx/latexaxis, while a horizontal reflection reflects a graph horizontally across the latexy/latexaxis The reflections are shown in Figure 9F ( 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
