Transformation Of Graph Dse Exercise
4‑Week DSE Graph Transformation Exercise Pack
Overview
A progressive set of exercises (4 weeks) for secondary students preparing for Hong Kong DSE (or equivalent) on graph transformations: translations, reflections, stretches/compressions, and combinations. Each week has objectives, worked examples, practice questions, and answers.
Note for students: Horizontal transformations are "opposite" of intuition: ( f(x+2) ) shifts left, ( f(2x) ) compresses horizontally. transformation of graph dse exercise

Example 2: Reflection and Shift
If ( f(x) = \sqrtx ), find equation after reflecting in y-axis then shifting right 2 units. Graph DSE (Node Merging) : Note for students:
