Math Problem Statement

Create a function graph to answer the question. Use the function graph to solve for the solutions to the equation x^2 + 2x = 3.

Solution

It seems you've uploaded an image that relates to solving the equation x2+2x=3x^2 + 2x = 3. 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 f(x)=x2+2x3f(x) = x^2 + 2x - 3 is shown above. From the graph, we can see that the function crosses the x-axis at two points: x=3x = -3 and x=2x = 2. These are the solutions to the equation x2+2x=3x^2 + 2x = 3, as the equation is equivalent to f(x)=0f(x) = 0.

The correct answer is:

  • x=2,0x = 2, 0

Let me know if you'd like further clarification or if you have any questions. Here are some related questions you might find interesting:

  1. How do you solve quadratic equations algebraically using the quadratic formula?
  2. What is the general form of a quadratic function?
  3. How can you determine the number of real solutions to a quadratic equation?
  4. What is the vertex of the parabola for the equation f(x)=x2+2x3f(x) = x^2 + 2x - 3?
  5. How does the value of the discriminant affect the nature of the solutions of a quadratic equation?

Tip: To find the vertex of a parabola, use the formula x=b2ax = -\frac{b}{2a} for a quadratic equation of the form ax2+bx+cax^2 + bx + c.
