Question 1208123
.
Suppose that the graph of a function f is known. Explain how the graph of
y = 4•f(x) differs from the graph of y = (1/4)f(x).
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



<pre>
    Graph y = 4*f(x) is obtained from the parent function graph by stretching  y-axis with coefficient 4.

    Graph y = (1/4)*f(x)  is obtained from the parent function graph by compressing y-axis with coefficient 4.
