Write codes to produce charts as shown below:

Answer :-

(a)

import matplotlib.pyplot as plt
import numpy as np

A = np.arange(2, 20, 2)
B = np.log(A)
plt.plot(A, B)
plt.plot(A  , B * 1.2)

plt.show()

(b)

import matplotlib.pyplot as plt
import numpy as np

A = np.arange(2, 20, 2)
B = np.log(A)
plt.plot(A, B)
plt.plot(A  , B * -1.2)
