This level is typical of longer questions (Paper 2), where multiple transformations are applied in sequence.
Think of transformations in two categories: (affects ) and Inside the bracket (affects 1. Vertical Transformations (The "Obedient" Changes) These happen outside . They do exactly what they look like. : Shift Up by : Shift Down by : Vertical Stretch (if ) or Compression (if : Reflection across the x-axis . 2. Horizontal Transformations (The "Opposite" Changes) These happen inside the . They do the opposite of what you expect. : Shift Right by units (Yes, minus means right!). : Shift Left by : Horizontal Compression (if ) or Stretch (if : Reflection across the y-axis . 🛠️ Step-by-Step Strategy for DSE Questions When you see a complex transformation like , follow this order to avoid mistakes: 📥 Step 1: Handle the "Inside" (x-axis) Move the graph left or right first. Example: For , add 3 to every -coordinate. 📈 Step 2: Handle Stretches/Reflections Multiply the coordinates. If there is a negative sign, flip the graph over the axis. 📤 Step 3: Handle the "Outside" (y-axis) Look at the +kpositive k at the very end. Move the whole shape up or down. Example: For +1positive 1 , add 1 to every -coordinate. 💡 Pro-Tips for the Exam transformation of graph dse exercise
Modifying vertex (node) and edge types to accommodate new data requirements without breaking existing queries. This level is typical of longer questions (Paper
. Which of the following equations represents the graph if it is and translated downwards by 5 units ? Solution Steps: Original Graph: Reflect in -axis: Replace −xnegative x . New equation: They do exactly what they look like
