TopicCurve Sketching
TypeSingle transformation application
DifficultyEasy -1.2 This is a straightforward application of a single transformation rule requiring students to substitute (x-1) for x and subtract 4 from the function. It's a 2-mark question testing basic recall of translation mechanics with minimal algebraic manipulation needed.
