I need help explaining the changes between y = |x| and y= |2x-1|. I need to comment on what the 2 and the 1 do to the original graph of y=|x|.
-----------------------
Regarding y = |x|, notice that y is zero when x=0.
---
Regarding y = |2x-1|, y will be zero when 2x-1=0
: that is when x = 1/2.
--
Starting with "x",
the 2 is applied 1st, so all the y-values are multiplied by 2:
that narrows the graph of y = |x|.
---
The -1 is then applied; that moves the graph to the right.
---
I'll graph the two functions on the same axes:
