![]() ![]() Positive to negative or negative to positive and the value of y remains constant. In the horizontal type of reflection, the graph of a function moves left or right only because only the value of x have to be changed that is from In this case, which means that the graph is not shifted to the left or right. Reflections in the y-axis y f ( x ) + a translate up/down by the vector ( 0 a ) y f ( x + a ) translate left/right by the vector ( a 0 ) y. In this type of reflection, the graph of a function moves up or down only because only the value of y have to be changed that is from positive to negative or negative to positive and the value of x remains constant. The vertical reflection is the simplest one. Triangle DEF is formed by reflecting ABC across the y-axis and has vertices D (4, -6), E (6, -2) and F (2, -4). The X-Shear preserves the Y coordinate and changes are made to X coordinates, which causes the vertical lines to tilt right or left as shown in below figure. Left or from either top to bottom or bottom to top. A reflection across the y-axis changes the position of the x-coordinate of all the points in a figure such that (x, y) becomes (-x, y). In Exercises 13 and 14, write a rule for g. Reflection of function means shifting of function either from left to right or right to f(x) -5x - 1 reflect in X axis then up 2 vertical stretch f-5 then down I. Vertical reflection causes the mirror image of the original function along the X coordinate axis. Horizontal reflection causes the mirror image of the original function along the Y coordinate axis. ![]() ![]() First one is the vertical reflection and second one is the horizontal reflection. It can bd done along X coordinate axis, Y coordinate axis or along the line. Reflection of a function can be carried out by changing the sign of the input element. To create the mirror image of an original function, reflection of a function comes into play. Understand the formulas for reflection over the x-axis, y-axis, the origin, and line yx, and see graphs with examples. ![]()
