How do you calculate a vertical shrink?
When the graph gets wider, it is either a vertical shrink or a horizontal stretch: essentially, shrinking TO the x-axis or stretching AWAY from the y-axis. So, in conclusion: if the graph moves on the y-axis: if the graph gets wider: vertical shrink. if the graph gets narrower: vertical stretch.

- I am not sure what you mean by moving and not moving on the y-axis. If you have some function such as g(x)= a f(bx-c) + d, each of a, b, c and d ha...
- 𝑓(𝑥) = 2 − 𝑥² Changing 𝑥 to 𝑘𝑥, we get 𝑓(𝑘𝑥) = 2 − (𝑘𝑥)² Just like if we changed 𝑥 to 3, we would get 𝑓(3) = 2 − 3²

- Say f(x)=x². If you make k=3, then f(k*x)=(3x)²=9x², while k*f(x)=3x². When the scalar is inside with the x, your replace x with everything inside...
- So (x-2)^2 is all positive, but by adding the -1, it shifts it down 1 (vertex at (2,-1)). Since it is negative in the domain of 1 to 3, the equatio...

To stretch or shrink the graph in the y direction, multiply or divide the output by a constant. 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 are the graphs of y = f (x), y = 2f (x), and y = x.

You must be wondering what does scaling mean in Math? Scaling is a procedure through which we draw an object that is proportional to the actual size of the object. Scaling in geometry means that we are either enlarging or shrinking figures so that they retain their basic shape. When we scale figures, they are known as similar figures. In the above ...
Scale is the ratio to represent the relation between the dimensions of a model or scaled figure and the corresponding dimensions of the actual figure or an object. Scale factor, on the other hand, is a number by which all the components of an object are multiplied in order to create an enlarged or reduced figure. Scale and scale factor are mostly u...
1. Scale up
We scale up when we want to enlarge a smaller figure to a bigger one. In other words, when the size of the figure is increased, it means it has scaled up. When we scale up, the scale factor can be calculated using the following formula: Scale Factor = Dimensions of the new shape Dimensions of the original shape Scale up factor = Larger figure dimensions ÷ Smaller figure dimensions We prefer to scale up when the object is very small. For example, we have to draw a butterfly on a piece of paper...
2. Scale down
We scale down when we want to reduce a bigger figure to a smaller one. In this case, the scale factor can be calculated using the following formula: Scale Factor = Dimensions of the new shape Dimensions of the original shape Scale down factor = Smaller figure dimensions ÷ Larger figure dimensions For example, we have to construct a bedroom of size 180 inches by 168 inches. We need to draw its blueprint first to set up the furniture, like bed, nightstands, etc. So, we will scale down the bedro...
Example 1. There are two similar pentagons given below. Find the scale factor. Solution: Scale Factor = 240=120 Example 2. What will be the height of the actual object if the height of the contracted figure is 4 units and the scale is 1:25? Solution: ScaledheightActualheight=125 4Actualheight=125 Actual height = 4×25= 100 units Example 3. What is t...
May 30, 2024 · Vertical scaling (stretching/shrinking) is intuitive: for example, y = 2f(x) doubles the y-values. Horizontal scaling is COUNTER-intuitive: for example, y = f(2x) DIVIDES all the x-values by 2. Find out why!
- Horizontal and Vertical Shifts. Horizontal and Vertical Shifts: Vertical Shifts. On the top left we have a vertical shift up. On the top the right we have a vertical shift down.
- Stretch vs Shrink (Compression) - Horizontal and Vertical. Stretch vs Shrink: Vertical Stretch vs Vertical Shrink (Compression) On the top left we have a vertical shrink or compression.
- Reflection Over the Axes. Reflection Over the Axes: Reflection Over the X-axis. On the left we have a reflection over the x-axis. When we reflect over the x-axis we change the output since the x-values remain the same.
- Example 1. Example 1: The first step is to graph our original function, f(x) = x2 - the black graph. The second step that we are going to add is the horizontal shrink by a factor of 2 - the blue graph.
Dilation in geometry is a transformation done by either shrinking or enlarging a figure, while maintaining the shape. Learn the properties, examples, and more.
“Shrinking” scores by a percentage results in a better estimate of the true mean. Shrinkage is where extreme values in a sample are “shrunk” towards a central value, like the sample mean. Shrinking data can result in: Better, more stable, estimates for true population parameters, Reduced sampling and non-sampling errors,
