Final answer:
The largest intervals on which the existence and uniqueness theorem guarantees a unique solution for the given initial conditions.
Step-by-step explanation:
The interval a < t < b on which the existence and uniqueness theorem for first order linear differential equations guarantees the existence of a unique solution depends on the initial conditions. For the given initial conditions:
- y(-7) = -5.5: The largest interval is from t = -7 to t = -0.5
- y(-0.5) = 6.4: The largest interval is from t = -0.5 to t = 0
- y(0) = 0: The largest interval is from t = 0 to t = 5.5
- y(5.5) = -3.14: The largest interval is from t = 5.5 to t = 10
- y(10) = 2.6: The largest interval is from t = 10 to t = 74
