What will be the output of this SciPy code snippet?
from scipy.optimize import minimize

result = minimize(lambda x: (x + 5)**2, 2)
print(round(result.x[0], 2))
A-5.0
B2.0
C0.0
D7.0
Step-by-Step Solution
Solution:
  1. Step 1: Analyze the function

    The function to minimize is (x + 5)^2, which has its minimum at x = -5.
  2. Step 2: Initial guess

    The initial guess is 2, but the optimizer will find the minimum at -5.
  3. Step 3: Output

    The result.x[0] will be approximately -5.0 after optimization.
  4. Final Answer:

    -5.0 -> Option A
  5. Quick Check:

    Minimum of (x+5)^2 is at x = -5 [OK]
Quick Trick: Minimum of (x + c)^2 is at -c [OK]
Common Mistakes:
  • Confusing initial guess with solution
  • Misinterpreting the lambda function
  • Ignoring the sign inside the squared term
