f%28x%29=abs%28x%29
recall:
f%28x%29=a%2Aabs%28x%29
a is vertical stretch/compression
abs%28a%29%3E+1 -> stretches
abs%28a%29%3C+1 -> compresses
a+%3C+0 flips the graph upside down
So, we must find the new equation of the vertical stretch of a factor of 4 such that the new equation yields,
f%28x%29+=+4abs%28x+%29
