The 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 aF ( 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 axisThe rule for a reflection over the x axis is (x,y)→(x,−y) What is true reflection?

Apply a reflection over the line x=3 Since the line of reflection is no longer the xaxis or the yaxis, we cannot simply negate the x or yvalues This is a different form of the transformation Let's work with point A first Since it will be a horizontal reflection, where the reflection is over x=3, we first need to determine the distance of the xvalue of point A to the line of reflectionWrite the equation for the final transformed graph of f after the indicated transformations are applied to its graph f(x) = 4\sqrt{x}, reflect in the yaxis and shift upwards 5 unitsFig 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 the left gets reflected to the right In other words—every x becomes −x Only the yintercept is invariant The equation of the reflection of f(x) about the yaxis is y = f(−x)

Rewrite the equation by factoring out a 1 from the exponent to read From the equation, you can see that the horizontal shift will be to the left 10 units and there will be a reflection over the yaxisTherefore, reflect the graph of over the yaxis and then shift (move) the reflected graph left 10 unitsReflection over the xaxis is a type of linear transformation that flips a shape or graph over the xaxis Every point above the xaxis is reflected to its corresponding position below the xaxis;Geometry reflection A reflection is a flip of an object over a line Let's look at two very common reflections a horizontal reflection and a vertical reflection

The reflection of such a parabola over the xaxis is simply written as y = (x^2) In other words, the function of f ( x ) becomes f ( x ) when reflected over the x axisReflection over x axis equation Since the reflection applied is going to be over the xaxis that means negating the yvalue For example if we begin by graphing the parent function latexfleftxright2xlatex we can then graph the two reflections We are not concerned about other transformations that take F x displaystyle fleft xright f x a new functionIdentifying coordinates of figures' reflections In this lesson students examine the impact on coordinates when a figure is reflected over the xaxis and yaxis They also learn to apply algebraic representations and analyze graphed images Students learn that a reflection is a mirror image of a figure over the line of reflection

Remember that when a point P (x, y) of the coordinate plane is reflected in the y axis , it becomes the point Q (x, y) and when reflected in x axis, it becomes P' (x, y) Therefore the quadratic p (x) = ax^2 bx c (a not zero) when reflected in y axis it becomes ;I start with e^x which is a curve that follows y=0 then starts to rise more abruptly at x=0 If f (x) Makes you reflect over the x axis Then e^x will do a neccesary reflection for reflecting it about y = 2 Then I add 2 to the end of f (x) = (e^x)2 = 2e^x Although on my homework they say the correct answer is 4 e^xReflection across the yaxis y = f ( − x) y = f (x) y = f ( − x) Besides translations, another kind of transformation of function is called reflection If a reflection is about the yaxis, then, the points on the right side of the yaxis gets to the right side of the yaxis, and vice versa Basic Concepts

And also, the line x = 2 (line of reflection) is the perpendicular bisector of the segment joining any point to its image Students can keep this idea in mind when they are working with lines of reflections which are neither the xaxis nor the yaxisWhen 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 reflection over the line y=x By following the notation, we would swap the xvalue and the yvalueReflection 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) \rightarrow (B, A ) $

Odd Function A function f f is called an odd 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 odd if performing a reflection about the y y axis and x x axis (doesn't matter which is performed first) does not change the graph of the function To help remember the definitionWhen you reflect a point across the yaxis, the ycoordinate remains the same, but the xcoordinate is transformed into its opposite When working with the graph of y = f (x), replace x with x Reflection in y = x When you reflect a point across the line y = x, the xcoordinate and the ycoordinate change placesThe relection of the graph of f( x,y) = 0 in the xaxis is f(x, —y) = 0 So the image of the line y=2x in the xaxis is —y = 2x or y = —2x
