## How do you tell if a graph is vertically stretched or compressed?

**How To: Given a function, graph its vertical stretch.**

- Identify the value of a .
- Multiply all range values by a .
- If a>1 , the graph is stretched by a factor of a . If 0<a<1 0 < a < 1 , the graph is compressed by a factor of a . If a<0 , the graph is either stretched or compressed and also reflected about the x -axis.

## What is the difference between stretch and compression?

**To stretch the function, multiply by a fraction between 0 and 1.**

**To compress the function, multiply by some number greater than 1**.

## Is a horizontal compression the same as a vertical stretch?

## What is the vertical stretch?

**occurs when a base graph is multiplied by a certain factor that is greater than 1**. This results in the graph being pulled outward but retaining the input values (or x). When a function is vertically stretched, we expect its graph’s y values to be farther from the x-axis.

## How do you know if it is a horizontal or vertical stretch?

## How do you find the vertical stretch on a graph?

## What is vertical stretch and horizontal stretch?

## What’s the difference between vertical and horizontal?

**vertical is the opposite of horizontal**, anything that makes a 90-degree angle (right angle) with the horizontal or the horizon is called vertical. So, the horizontal line is one that runs across from left to right.

## What is horizontal compression?

**when the function’s base graph is shrunk along the x-axis and, consequent, away from the y-axis**.

## How do you know when to stretch or shrink?

## What is a vertical stretch by a factor of 2?

## What are two types of compression?

**lossless and lossy**. Lossless compression algorithms reduce the size of files without losing any information in the file, which means that we can reconstruct the original data from the compressed file.

## What is another word for compression?

Some common synonyms of compress are

**condense, constrict, contract, deflate, and shrink**.## What is an example of compression?

**When a pile of material is squished together and made smaller and more dense**, this is an example of compression.

## How do you do horizontal compression?

## What does a horizontal stretch mean?

**when a base graph is widened along the x-axis and away from the y-axis**.

## What is the example of vertical structure?

**pyramidal top-down structure**, with a CEO, president or owner at the top, a middle section of managers and supervisors, and a bottom section of regular employees.

## What is an example of vertical?

**the motion of an apple falling from a tree**, would be vertical motion. Or the motion of a rocket or a balloon going from bottom to top is also classified as vertical.

## Is vertical or horizontal integration better?

**Horizontal integrations help companies expand in size, diversify product offerings, reduce competition, and expand into new markets**. Vertical integrations can help boost profit and allow companies more immediate access to consumers.
