The transformation of graphs is a fundamental topic in the DSE (Diploma of Secondary Education) Mathematics curriculum. Mastering this area is not just about memorizing formulas; it is about developing a visual intuition for how functions behave under various algebraic "stresses." Core Concepts of Graph Transformation
When tackling a "transformation of graph DSE exercise," students often get confused by the order of operations. Use these tips to stay organized: The "Inside-Out" Rule
by 2 compresses it. Transformations outside the function (affecting ) behave intuitively. Step-by-Step Breakdown Recognize the original
, it is a horizontal compression (the graph squishes toward the y-axis).
) usually behave the opposite of what you might expect. For example, adding to moves the graph left, and multiplying
Choose specific coordinates, such as the vertex or intercepts, and apply the transformations to those points one by one.
Translation involves moving the entire graph without changing its shape or orientation. , the graph moves up , the graph moves down Horizontal Shift: , the graph moves right units (e.g., moves 3 units right). , the graph moves left units (e.g., moves 3 units left). 2. Reflection: Flipping the Graph Reflection creates a mirror image of the original function. Reflection across the x-axis: All y-values change signs. The top becomes the bottom. Reflection across the y-axis:
Draw the new graph and check if the changes match the algebraic operations (e.g., did a actually flip it upside down?). Sample DSE Exercise Problem: Let be a function. If the graph of
Usually, it is easier to deal with shifts and stretches involving before moving to
