Math Problem Statement
Solution
It seems you've uploaded an image that relates to solving the equation . I will generate a graph of the related function and help you find the solutions. Give me a moment to process this. numpy as np import matplotlib.pyplot as plt
Define the function f(x) = x^2 + 2x - 3
def f(x): return x**2 + 2*x - 3
Generate x values
x_values = np.linspace(-5, 5, 400) y_values = f(x_values)
Plot the function
plt.figure(figsize=(6,6)) plt.plot(x_values, y_values, label=r'$f(x) = x^2 + 2x - 3$') plt.axhline(0, color='black',linewidth=1) plt.axvline(0, color='black',linewidth=1) plt.title('Graph of the function $f(x) = x^2 + 2x - 3$') plt.xlabel('x') plt.ylabel('f(x)') plt.grid(True) plt.legend() plt.xlim(-5, 5) plt.ylim(-5, 5) plt.scatter([2, -3], [0, 0], color='red') # Mark the roots plt.show()The graph of the function is shown above. From the graph, we can see that the function crosses the x-axis at two points: and . These are the solutions to the equation , as the equation is equivalent to .
