We can even reflect it about both axes by graphing y-f (-x). Describe the transformation which maps yln (x) to a. We can reflect the graph of any function f about the x-axis by graphing y-f (x) and we can reflect it about the y-axis by graphing yf (-x).
I would appreciate any advice upon my proposed solutions. The graph of y f (-x) is a reflection in the y axis. Transformations are used to change the graph of a parent function into the graph of a more complex function. 1 AN630078 242 25 Homework Statement Hello, I was practising describing graphical transformations with several example questions but there was one which I was especially unsure of. Stretching a graph means to make the graph narrower or wider. They are caused by differing signs between parent and child functions.Ī stretch or compression is a function transformation that makes a graph narrower or wider. The horizontal reflection produces a new graph that is a mirror image of the base or original graph about the y-axis. Reflections are transformations that result in a "mirror image" of a parent function. Another transformation that can be applied to a function is a reflection over the x or y-axis. Reflecting a graph means to transform the graph in order to produce a "mirror image" of the original graph by flipping it across a line. a transformation in which the distance of each x-coordinate or y-coordinate. All other functions of this type are usually compared to the parent function. Reflection: a transformation where each point of the original graph has an. Sketch the graph of each of the following transformations of y = xĪ stretch or compression is a function transformation that makes a graph narrower or wider, without translating it horizontally or vertically.įunction families are groups of functions with similarities that make them easier to graph when you are familiar with the parent function, the most basic example of the form.Ī parent function is the simplest form of a particular type of function.
Graph each of the following transformations of y=f(x). This occurs when we add or subtract constants from the x -coordinate before the function is applied. Answer: A horizontal translation is a rigid transformation that shifts a graph left or right relative to the original graph. Reflecting the graph vertically means that each output y-value will be reflected over the horizontal x-axis as shown in figure 10. Let y=f(x) be the function defined by the line segment connecting the points (-1, 4) and (2, 5). Solution: Begin with the basic function defined by f ( x) x and shift the graph up 4 units.
