Question 1

+3 marksOne correct option

Given the following code for Polynomial Regression:

python
from sklearn.preprocessing import PolynomialFeatures
from sklearn.linear_model import LinearRegression
import numpy as np


X = np.array([1, 2, 3, 4, 5]).reshape(-1, 1)
y = np.array([1, 4, 9, 16, 25])


poly = PolynomialFeatures(degree=2,interaction_only=False)
X_poly = poly.fit_transform(X)
model = LinearRegression()
model.fit(X_poly, y)


print(model.coef_)
