easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Identify parameters in polyfit
The functionpolyfittakesxandyas data points, anddegas the polynomial degree.Step 2: Match parameter to polynomial degree
Thedegparameter controls the degree of the polynomial to fit.Final Answer:
deg -> Option BQuick Check:
Degree parameter = deg [OK]
Quick Trick: Degree is always the third argument in polyfit [OK]
Common Mistakes:
- Confusing x or y as degree
- Using wrong parameter order
- Assuming degree is optional
