# What is compression and stretch?

**stretched**or

**compressed**vertically in relation to the graph of the original function. If the constant is greater than 1, we get a vertical

**stretch**; if the constant is between 0 and 1, we get a vertical

**compression**.

Furthermore, what is the difference between vertical stretch and compression?

**Vertical stretching** means the function is **stretched** out **vertically**, so it's taller. **Vertical compression** means the function is squished down **vertically**, so it's shorter. On the graph of a function, the F(x), or output values of the function, are plotted on the y-axis.

Furthermore, what is a compression in math? A **compression** occurs when a **mathematical** object is scaled by a scale factor less in absolute value than one. When a **compression** occurs, the image is smaller than the original **mathematical** object. If the scaling occurs about a point, the transformation is called a dilation and the "point" is called the dilation centre.

Hereof, how do you stretch and compress a graph?

We can also **stretch** and shrink the **graph** of a function. 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 ).

What are the 4 types of transformations?

There are four main types of transformations: **translation**, **rotation**, **reflection** and dilation.
