we're multiplying $\,x\,$ by $\,3\,$ before dropping it into the $\,f\,$ box. If a > 1 a > 1, then the, How to find absolute maximum and minimum on an interval, Linear independence differential equations, Implicit differentiation calculator 3 variables. Figure 3 . If you need an answer fast, you can always count on Google. With a parabola whose vertex is at the origin, a horizontal stretch and a vertical compression look the same. Create your account. Scanning a math problem can help you understand it better and make solving it easier. Make sure you see the difference between (say)
give the new equation $\,y=f(\frac{x}{k})\,$. This causes the $\,x$-values on the graph to be DIVIDED by $\,k\,$, which moves the points closer to the $\,y$-axis. At 24/7 Customer Support, we are always here to help you with whatever you need. Create a table for the function [latex]g\left(x\right)=\frac{3}{4}f\left(x\right)[/latex]. \end{align}[/latex]. This results in the graph being pulled outward but retaining Determine math problem. However, in this case, it can be noted that the period of the function has been increased. If the scaling occurs about a point, the transformation is called a dilation and the point is called the dilation centre. The constant in the transformation has effectively doubled the period of the original function. We now explore the effects of multiplying the inputs or outputs by some quantity. Because [latex]f\left(x\right)[/latex] ends at [latex]\left(6,4\right)[/latex] and [latex]g\left(x\right)[/latex] ends at [latex]\left(2,4\right)[/latex], we can see that the [latex]x\text{-}[/latex] values have been compressed by [latex]\frac{1}{3}[/latex], because [latex]6\left(\frac{1}{3}\right)=2[/latex]. $\,y = 3f(x)\,$, the $\,3\,$ is on the outside;
[beautiful math coming please be patient]
A point $\,(a,b)\,$ on the graph of $\,y=f(x)\,$ moves to a point $\,(\frac{a}{k},b)\,$ on the graph of. If 0 < a < 1, then aF(x) is compressed vertically by a factor of a.

Figure %: The sine curve is stretched vertically when multiplied by a coefficient. y = c f(x), vertical stretch, factor of c, y = (1/c)f(x), compress vertically, factor of c, y = f(cx), compress horizontally, factor of c, y = f(x/c), stretch horizontally, factor of c. The best way to learn about different cultures is to travel and immerse yourself in them. Did you have an idea for improving this content? When , the horizontal shift is described as: . For a vertical transformation, the degree of compression/stretch is directly proportional to the scaling factor c. Instead of starting off with a bunch of math, let's start thinking about vertical stretching and compression just by looking at the graphs. You can use math to determine all sorts of things, like how much money you'll need to save for a rainy day. A function [latex]P\left(t\right)[/latex] models the numberof fruit flies in a population over time, and is graphed below. Say that we take our original function F(x) and multiply x by some number b. Now we consider changes to the inside of a function. Vertical stretching means the function is stretched out vertically, so it's taller. Step 10. The y y -coordinate of each point on the graph has been doubled, as you can see . If b<1 , the graph shrinks with respect to the y -axis. 2) I have constantly had trouble with the difference between horizontal and vertical compression of functions, their identification, and how their notation works. Set [latex]g\left(x\right)=f\left(bx\right)[/latex] where [latex]b>1[/latex] for a compression or [latex]0
