No, it is similar to a parabola in vertex form:
y =I x-3 I +5 have a vertex at (3,5)
For this equation, when x=0, y=8, not the vertex.
y =I x-3 I +5 have a vertex at (3,5)
For this equation, when x=0, y=8, not the vertex.

Yes the origin of the absolute value has to be at the origin of were it hits the y/x axis.
