а) График функции y=x²+3:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(-10, 10, 100)
y = x**2 + 3

plt.figure(figsize=(8, 6))
plt.plot(x, y, label='y=x²+3')
plt.xlabel('x')
plt.ylabel('y')
plt.title('Graph of y=x²+3')
plt.grid(True)
plt.legend()
plt.show()

б) График функции y=(x+2)²-2:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(-10, 10, 100)
y = (x+2)**2 - 2

plt.figure(figsize=(8, 6))
plt.plot(x, y, label='y=(x+2)²-2')
plt.xlabel('x')
plt.ylabel('y')
plt.title('Graph of y=(x+2)²-2')
plt.grid(True)
plt.legend()
plt.show()
