The graph y=|x|-4 is obtained from the graph y=|x| dy <span>moving down 4 units the graph y=|x| along the y-axis (see, if x=0, then for y=|x|, y=0 and for y=|x|-4, y=-4).
</span>
These two graphs have the same form.

Sqrt (y^4 * y)
Sqrt y*4 = y^2
y^2 sqrt y
The decimal representation of 1/11 is 0.090909...
The pair of digits '09' repeat forever.
If you start counting the digits after the decimal point,
the odd ones are all zero, and the even ones are all 9 .
So the 44th digit after the decimal point is 9 .
