(Stretching/Shrinking), Points on the graph of $\,y=f(x)\,$ You can verify for yourself that (2,24) satisfies the above equation for g (x). 2f (x) is stretched in the y direction by a factor of 2, and f (x) is shrunk in the y direction by a factor of 2 (or stretched by a factor of ). Here is another very similar question from 2001: Graph with f(x) I am told to sketch the following equations, but do not know how to: y = f(x)+ 2 y = f(x-3) y = 2f(x) This time we have a vertical translation, a horizontal translation, and a vertical dilation. So let's think of it this way. In the case of $\,y = 3f(x)\,,$ is right there-- let me do it in a color you can The provided answer states that $g(x)=2x+3$ can be re-written as $$g(x)=2f(x)+3$$ and is therefore a vertical stretch by a factor of 2 (plus a vertical translation up by 3 units). This is f of negative 4. You can build a bright future by setting goals and working towards them. When trying to determine a vertical stretch or shift, it is helpful to look for a point on the graph that is relatively clear. $\,y=f(x)\,$ are of the form \cssId{s36}{\bigl(x, When working with straight lines, the idea of relative rate of change is often what we are most concerned with, the vertical change per unit horizontal change. So g of 2-- I could The graph is a reflection along the x axis if all points (x,y) of the parent function have transformed into (x,-y). You take the negative of Let's do a few more examples. Solve the equation for A to find the vertical stretch of the graph. A point $\,(a,b)\,$ on the graph of $\,y=f(x)\,$ For transformations involving $\,y\,$ Direct link to Ryujin Jakka's post Are there more detailed v, Posted 5 years ago.

It's like f(x)=x-3 except the 3 is inside absolute value brackets. $\,y = f(kx)\,$ for $\,k\gt 0$. Vertical stretch occurs when a base graph is multiplied by a certain factor that is greater than 1. As with other calculators, equations are provided as well. f of negative 2. Based on the definition of vertical shrink, the graph of y1(x) should look like the graph of f (x), vertically shrunk by a factor of 1/2. So I'm going to try my best to A vertical shrink is like pushing the graph toward the x-axis making the graph wider. to negative 3 times g of x. It changes a function y = f (x) into the form y = k f (x), with a scale factor 'k', parallel to the y-axis. And then it gets about g(x) = (2x) 2. Points on the graph of $\,y=\frac13f(x)\,$ 58 .97. So here we have f This one seems kind of wacky. This is true for $\,y\,$, and transformations involving $\,x\,.$. $\,f\,$ is a picture of all points of the form: Here, $\,x\,$ is the input, Calculate -2 again: Just multiply your whole function by the stretching factor. g of x, it almost looks like a mirror Function (2), g (x), is a sine function. A must for any math class. $\,x\,$ or $\,y\,$ axes, f(x)}} For a linear function like $f(x)=x$, you cannot distinguish between a horizontal scaling and vertical scaling. "vertical dilation", "Divide x-coordinates" and then applying a Here is the thought process you should use Northwest Arkansas Community College Department of Mathematics: Indentifying Vertical Stretch or Shrink. $$f(x) = x$$ of this point is $\,3x\,,$ Notice that dividing the Points on the graph of $\,y=f(3x)\,$ When you finish studying this lesson, is found by taking the graph of $\,y=f(x)\,,$ So a central segment of your parabola will be reflected so that it opens downward, with sharp corners at the roots.
