Question

Given the parent function of y=|x|, state the type of transformation that occured to get the function below. y=1/4|x|

Answer 1

For this case we have the following function:
 y = | x |
 Vertical expansions and compressions:
 To graph y = a * f (x)
 If 0 <a <1, the graph of y = f (x) is compressed vertically by a factor a. (Shrinks)
 We have then that applying the transformation results:
 y = 1/4 | x |
 Answer:
 it is compressed vertically by a factor 1/4
