TopicFunction Transformations
TypeForward transformation (single point, multiple transformations)
DifficultyModerate -0.8 This is a straightforward application of standard transformation rules requiring only recall and substitution. Each part involves a single, well-known transformation (horizontal stretch, combined horizontal translation and vertical stretch, reflection of negative values). No problem-solving or conceptual insight is needed—students simply apply memorized formulas to transform the coordinates.
Spec1.02w Graph transformations: simple transformations of f(x)

  1. The point \(P ( - 4 , - 3 )\) lies on the curve with equation \(y = \mathrm { f } ( x ) , x \in \mathbb { R }\)
Find the point to which \(P\) is mapped when the curve with equation \(y = \mathrm { f } ( x )\) is transformed to the curve with equation
  1. \(y = \mathrm { f } ( 2 x )\)
  2. \(y = 3 \mathrm { f } ( x - 1 )\)
  3. \(y = | f ( x ) |\)
