Sketch the graphs of the absolute value function and state the range
{(x,y): y=|3x-6|, x∈R}

The graph is shown below. It consists two straight lines, i.e. y = 3x - 6 for x ≥ 2, and y = -3x + 6 for x < 2.

The range is {y ∈ R | y > 0}.

Two steep rays,
one going from (2,0) out through (3,3) and then straight on;
the other going fro (2,0) out through (1,3) and then straight on.
