Introduction
Graphing a quadratic equation is an essential skill in mathematics, and it can be used to model various real-world situations. In this article, we will focus on graphing the equation , including the roots and the vertex. We will use the concept of factoring, completing the square, and the properties of quadratic functions to graph the equation.
Understanding the Equation
The given equation is a quadratic equation in the form of , where , , and . The coefficient of the squared term, , is negative, which means that the parabola will open downwards.
Finding the Roots
To find the roots of the equation, we need to factorize the quadratic expression. We can start by finding two numbers whose product is equal to the product of the coefficient of the squared term and the constant term, and whose sum is equal to the coefficient of the linear term.
import sympy as sp

x = sp.symbols('x')
equation = -x**2 + 12*x - 35
roots = sp.solve(equation, x)
print(roots)
The output of the above code will be [5, 7]
, which are the roots of the equation.
Finding the Vertex
The vertex of a parabola is the point where the parabola changes direction. To find the vertex, we can use the formula x = -b / 2a
, where a
and b
are the coefficients of the squared term and the linear term, respectively.
# Define the coefficients
a = -1
b = 12
x_vertex = -b / (2 * a)
print(x_vertex)
The output of the above code will be 6
, which is the x-coordinate of the vertex.
Graphing the Equation
Now that we have found the roots and the vertex, we can graph the equation. We can use a graphing calculator or a computer program to graph the equation.
import matplotlib.pyplot as plt
import numpy as np
x_values = np.linspace(-10, 10, 400)
y_values = -x_values**2 + 12*x_values - 35
plt.plot(x_values, y_values)
plt.scatter([5, 7], [0, 0], color='red')
plt.scatter([6], [-1], color='green')
plt.xlabel('x')
plt.ylabel('y')
plt.title('Graph of the Equation ')
plt.grid(True)
plt.axhline(0, color='black')
plt.axvline(0, color='black')
plt.show()
The above code will create a graph of the equation, including the roots and the vertex.
Conclusion
In this article, we have graphed the equation , including the roots and the vertex. We have used the concept of factoring, completing the square, and the properties of quadratic functions to graph the equation. We have also used a graphing calculator or a computer program to graph the equation.
