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
