Easy -1.2 This is a straightforward graph sketching question requiring only basic knowledge of absolute value transformations. Students need to identify the V-shape with vertex at x = -a/2, y-intercept at a, and x-intercept at -a/2, all of which follow directly from the definition of |2x + a|. It's simpler than average A-level questions as it involves no calculus, no problem-solving, and is a standard textbook exercise.
Sketch the graph of \(y = |2x + a|\), where \(a\) is a positive constant.
Show clearly where the graph intersects the axes.
