Math Problem Statement

(X3+1)/x2_1 draw graph

Solution

It looks like you want to graph the function:

f(x)=x3+1x21f(x) = \frac{x^3 + 1}{x^2 - 1}

I'll generate the graph for you. numpy as np import matplotlib.pyplot as plt

Define the function

def f(x): return (x3 + 1) / (x2 - 1)

Define x values avoiding division by zero at x = ±1

x = np.linspace(-3, 3, 400) x = x[x != -1] # Remove x = -1 x = x[x != 1] # Remove x = 1

Compute y values

y = f(x)

Plot the function

plt.figure(figsize=(8, 6)) plt.plot(x, y, label=r'$f(x) = \frac{x^3 + 1}{x^2 - 1}$', color='b')

Mark vertical asymptotes at x = ±1

plt.axvline(x=-1, color='r', linestyle='dashed', label='Asymptote $x = -1$') plt.axvline(x=1, color='r', linestyle='dashed', label='Asymptote $x = 1$')

Add labels and title

plt.xlabel('x') plt.ylabel('f(x)') plt.title('Graph of $f(x) = \frac{x^3 + 1}{x^2 - 1}$') plt.legend() plt.grid()

Show the plot

plt.show()Here is the graph of f(x)=x3+1x21f(x) = \frac{x^3 + 1}{x^2 - 1}. The function has vertical asymptotes at x=±1x = \pm 1, where the denominator equals zero. Let me know if you want any details!
