Introduction

In mathematics, a quadratic function is a polynomial function of degree two, which means the highest power of the variable is two. The standard form of a quadratic function is given by the equation f(x)=ax2+bx+cf(x) = ax^2 + bx + c, where aa, bb, and cc are constants. However, there is another form of a quadratic function called the vertex form, which is given by the equation f(x)=a(xh)2+kf(x) = a(x - h)^2 + k, where (h,k)(h, k) is the vertex of the parabola. In this article, we will learn how to convert a quadratic function from standard form to vertex form.

Converting from Standard Form to Vertex Form

To convert a quadratic function from standard form to vertex form, we need to complete the square. This involves rewriting the quadratic function in a way that allows us to easily identify the vertex of the parabola.

Step 1: Identify the Coefficients

The first step is to identify the coefficients aa, bb, and cc in the standard form of the quadratic function. In this case, we have a=2a = 2, b=8b = 8, and c=11c = 11.

Step 2: Write the Quadratic Function in the Form f(x)=a(x+b/2a)2+cb2/4af(x) = a(x + b/2a)^2 + c - b^2/4a

Now, we need to write the quadratic function in the form f(x)=a(x+b/2a)2+cb2/4af(x) = a(x + b/2a)^2 + c - b^2/4a. This involves adding and subtracting a constant term inside the parentheses.

import math

a = 2 b = 8 c = 11

constant_term = (b**2) / (4 * a)

vertex_x = -b / (2 * a) vertex_y = c - constant_term

print(f"The vertex is ({vertex_x}, {vertex_y})")

Step 3: Simplify the Expression

Now that we have written the quadratic function in the form f(x)=a(x+b/2a)2+cb2/4af(x) = a(x + b/2a)^2 + c - b^2/4a, we can simplify the expression by evaluating the constant term.

# Simplify the expression
simplified_expression = f"2(x + {b / (2 * a)})^2 + {c - (b**2) / (4 * a)}"

print(f"The simplified expression is {simplified_expression}")

Step 4: Write the Quadratic Function in Vertex Form

Now that we have simplified the expression, we can write the quadratic function in vertex form.

# Write the quadratic function in vertex form
vertex_form = f"f(x) = 2(x + {b / (2 * a)})^2 + {c - (b**2) / (4 * a)}"

print(f"The vertex form is {vertex_form}")

Conclusion

In this article, we learned how to convert a quadratic function from standard form to vertex form. We used the method of completing the square to rewrite the quadratic function in a way that allows us to easily identify the vertex of the parabola. We also used Python code to simplify the expression and write the quadratic function in vertex form.

The Final Answer

The final answer is f(x)=2(x+2)2+3\boxed{f(x) = 2(x + 2)^2 + 3}.
