Interval analysis breaks down the entire domain of a function into smaller parts to study its behavior more deeply, which is incredibly useful for piecewise functions.
In this context, we're interested in the intervals \(0 \leq t \leq 1\), \(1 < t \leq 2\), and \(2 < t \leq 3\). For each segment, the focus is:
- Evaluating the individual function piece on its respective interval.
- Observing how these segments gel together at their boundaries.
During our analysis, we note the unique expression for each interval and judge how they contribute to the entire graph's continuity:- Each section operates continuously within itself.- It is at their boundaries—transition points—where the overall function's behavior is observed.Interval analysis ensures one grasps the detailed and expansive picture of how seamless or broken a function might be, helping to label it correctly as either continuous, piecewise continuous, or neither.
