What is compression and stretch?
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.
