How to graph this function?

Question

If f(x) = x^2 - 2x, then how would I graph f([x])? this is the absolute of the x on the inside of f(x).

Answer 1

On the right side of the y axis:
Part of a parabola with vertex at (1, -1) including the origin, and intersecting the x axis at (2, 0). And "opening up".

On the left side of the x axis:
Mirror image of the other side. Part of a parabola with vertex at (-1, -1) and intersecting the x axis at (-2, 0). Also opening up.
