desribe how the graph of each funtion compares to the graph of y = l x l (absolute value)
a) y = 1 2x l
b) y = l 1/2x l
c) 2y = l x l
d) 1/2y = l x l
i don't understand when it is vertical/horizontal and when it is expansion or compression

a is expanded, y is twice what it was before for any x.
d) is expanded, y is (2abs x ) twice what it was before.
