When we multiply a function by a positive constant, we get a function whose graph is 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.
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 ).
There are four main types of transformations: translation, rotation, reflection and dilation.
