hard📝 Application Q8 of 15
Step-by-Step Solution
Solution:
Step 1: Identify boundaries and neighbors for 0.0 to 1.0
Boundaries: 0.0 and 1.0; neighbors: just below 0.0 (−0.1) and just above 1.0 (1.1), plus values just inside boundaries (0.1, 0.9).Step 2: Check which option includes boundaries and neighbors
−0.1, 0.0, 0.1, 0.9, 1.0, 1.1 includes −0.1, 0.0, 0.1, 0.9, 1.0, 1.1 correctly covering boundaries and neighbors.Final Answer:
−0.1, 0.0, 0.1, 0.9, 1.0, 1.1 -> Option BQuick Check:
Decimal boundaries plus neighbors = −0.1, 0.0, 0.1, 0.9, 1.0, 1.1 [OK]
Quick Trick: Include decimal neighbors just outside boundaries [OK]
Common Mistakes:
- Ignoring decimal neighbors outside boundaries
- Testing only whole numbers
- Missing boundary decimal values
