    "term": "analysis",
    "definition": "Derivative sign charts organize global behavior. Critical numbers, endpoints, and nondifferentiable points divide the domain into intervals where monotonicity and concavity can be tested."

  {
    "term": "optimization",
    "definition": "Optimization converts constraints into a one-variable objective, identifies the feasible domain, and compares all candidates—including endpoints. The final result must be interpreted in context."
