import numpy as np
import matplotlib.pyplot as plt

定义x的范围

x = np.linspace(-10, 10, 400)

创建一个2行3列的子图布局

fig, axs = plt.subplots(2, 3, figsize=(12, 8))

遍历每个子图

for k, ax in enumerate(axs.flat, start=1):
y = k * x**2 + 2*k
ax.plot(x, y, label=f'$y = {k}x^2 + 2{k}$')
ax.set_title(f'k = {k}')
ax.legend()
ax.grid(True)

调整子图之间的间距

plt.tight_layout()

显示图形

plt.show()

print("学号：3025")
