Transformation Of | Graph Dse Exercise [exclusive]
Graph transformation is a fundamental topic in analytic geometry and function analysis. For DSE candidates, mastering graph shifts, reflections, stretches, and compressions is essential for solving complex function problems quickly without plotting every point.

Look for the option in the multiple-choice selection that has moved slightly to the left and is inverted. 4. Common Traps and Exam Tips Confusing
Instead of tracking the entire curve visually, track specific "anchor points" such as vertices, -intercepts, or -intercepts. If a point , it becomes , it becomes , it becomes Step 3: Handle the "Inside" Operations Carefully When converting , always factor out the coefficient of first to clearly see the true horizontal shift.

Choosing the right representation dictates your transformation efficiency. For sparse graphs (
Use these to drill before exams.

At its heart, function transformation involves applying a mathematical operation to a known base function (like a quadratic or trigonometric function), which predictably alters its graph. The ultimate goal is often to determine the equation of a new graph or to visualize changes based on an equation.
In the HKDSE Mathematics curriculum, is a critical topic frequently appearing in Paper 1 (Section A and B) and Paper 2 (Multiple Choice). It involves changing a parent function
| Transformation | New Equation | Effect on Graph | | :--- | :--- | :--- | | | $y = f(x) + k$ | Shift up by $k$ units (if $k > 0$). | | | $y = f(x) - k$ | Shift down by $k$ units. | | Horizontal Translation | $y = f(x - k)$ | Shift right by $k$ units. | | | $y = f(x + k)$ | Shift left by $k$ units. | | Reflection | $y = -f(x)$ | Reflect about the x-axis . | | | $y = f(-x)$ | Reflect about the y-axis . | | Scaling (Stretch/Compress) | $y = k \cdot f(x)$ | Vertical stretch by factor $k$ (if $k > 1$). | | | $y = f(kx)$ | Horizontal compression by factor $\frac1k$. | Graph transformation is a fundamental topic in analytic
Write equation after 3 steps. Then reverse to find original.
Moving a property from an edge to a vertex, or vice versa, to improve filtering efficiency.
