A reflection across xaxis is nothing but folding or flipping an object over the x axis The original object is called the preimage, and the reflection is called the image If the preimage is labeled as ABC, then t he image is labeled using a prime symbol, such as A'B'C' An object and its reflection have the same shape and size, but the figures face in opposite directionsThe effect of the reflection was to change the major axis of the ellipse from horizontal to vertical When the line of reflection is the xaxis, the ycoordinates will be equal, but the xcoordinates will be opposites x' = x and y' = yReflection across the xaxis y = − f ( x) y = f (x) y = − f ( x) The concept behind the reflections about the xaxis is basically the same as the reflections about the yaxis The only difference is that, rather than the yaxis, the points are reflected from above the xaxis to below the xaxis, and vice versa Basic Concepts

You have two choices to reflect either reflect across the yaxis or the yaxis In either case you need the negative of the opposite value In other words if you want to reflect across the xaxis then you need the opposite of the y value VicevThus for y = f ( x), the reflection about the line y = x is accomplished by x = f ( y) For example, the reflection about the line y = x for y = x 2 is the equation x = y 2 Hope it helps If the curve is complicated, you can just take particular, interesting points and switch the coordinatesY axis) Reflection over line y=x or y=Reflection over line y=x or y=xx Reflection over y=x Point (x,y) reflects to point (y,x) Reflection over line y=x

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 ;For this type of reflection, all you have to do is switch the x and y values if a point is (4,2), then the inverse is (2,4) If you begin with a function y=sqrt (x), there are many different lines you could reflect this function across, but only reflecting over y=x will give you the inverse of the function y=xThe best way to practice drawing reflections over y axis is to do an example problem Example Given the graph of y = f (x) y=f(x) y = f (x) as shown, sketch y = f (− x) y = 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
