💡 Today, let's decode Function Transformations! The golden rule: changes INSIDE the parentheses (f(x−2)) shift the graph HORIZONTALLY — and counterintuitively! WHY? Because x−2 = 0 happens at x = 2, so the graph moves RIGHT. ❌ Common mistake: f(x+3) shifts LEFT (not right!) — inside changes go the "opposite" way. ✅ f(x)+3 shifts UP 3 — outside changes do exactly what they say! 💡 #MathFoundations #AlgebraSkills #ProblemSolving #FunctionTransformations
