Two routes to the turning point, the four questions a complete graph answers, and a worked sketch from start to finish.
The parabola as the graph of a second-degree function, how the leading coefficient decides its direction, and reading the range from the turning point.
The V-shaped graph of y = |x|, how shifts and reflections move it, and a method for sketching any transformed version.
