Let us start with a function, in this case it is f(x) = x 2, but it could be anything f(x) = x 2 Here are some simple things we can do to move or scale it on the graph We can move it up or down by adding a constant to the yvalue g(x) = x 2 C Note to move the line down, we use a negative value for C C > 0 moves it up;PUSHING THE XREFLECTION BUTTON FLIPS FUNCTIONS ABOUT THE YAXIS y = f(– x) Do you see how the negative sign is on the inside of the function affecting the xvalue of the function?Swap places of x and y around True for any graph ln (x) is a reflection of e^x due to the same procedure 0 reply X start new discussion

Functions of graphs can be transformed to show shifts and reflections Graphic designers and 3D modellers use transformations of graphs to design objects and imagesGraph functions using reflections about the xaxis and the yaxis Another transformation that can be applied to a function is a reflection over the x – or y axis A vertical reflection reflects a graph vertically across the x axis, while a horizontal reflection reflects a graph horizontally across the y Reflections Suppose that an engineer, Bob, has a blueprint containing a graph of the following function f(x) = x 2 2x 3 ;
