[Solved] Identify the error in this SciPy code that tries to find the root of f(x) = x^2 - 4:from scipy.optimize import root def f(x): return x**2 - 4 result = root(f, x0=0) print(result.root) | SciPy

SciPy - Advanced Optimization

Identify the error in this SciPy code that tries to find the root of f(x) = x^2 - 4:

from scipy.optimize import root

def f(x):
    return x**2 - 4

result = root(f, x0=0)
print(result.root)

AInitial guess x0=0 is not suitable for root finding here.

BFunction f must return a list, not a number.

CThe root function is called incorrectly; it needs extra parameters.

DThere is no error; code runs correctly.

Step-by-Step Solution

Solution:

Step 1: Check function and root call
Function f returns a number, which is valid for scalar root finding. root() is called with correct syntax.
Step 2: Verify initial guess and output
Initial guess x0=0 is valid; root() will find root near 0 (which is 2 or -2). Code runs without error.
Final Answer:
There is no error; code runs correctly. -> Option D
Quick Check:
Function and root call are correct [OK]

Quick Trick: Check function return type and root call syntax [OK]
