Understanding the Basics of Quadratic Functions

Quadratic functions are a fundamental concept in mathematics, and they play a crucial role in various fields, including algebra, geometry, and calculus. A quadratic function is a polynomial function of degree two, which means the highest power of the variable is two. The general form of a quadratic function is f(x) = ax^2 + bx + c, where a, b, and c are constants, and x is the variable.

The Given Equation and Its Components

In this problem, we are given a quadratic function in the form f(x) = (x - [?])^2 + [?]. To solve for the missing values, we need to understand the components of the equation. The first part of the equation, (x - [?]), represents a binomial expression, where [?] is a constant that needs to be determined. The second part of the equation, [?], is a constant that also needs to be determined.

Identifying the Missing Values

To identify the missing values, we need to analyze the given equation and look for patterns or relationships between the components. One way to approach this problem is to consider the properties of quadratic functions. A quadratic function can be written in the form f(x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

Vertex Form of a Quadratic Function

The vertex form of a quadratic function is a useful way to represent a quadratic function, as it provides information about the vertex of the parabola. In this form, the equation is written as f(x) = a(x - h)^2 + k, where a is the coefficient of the squared term, h is the x-coordinate of the vertex, and k is the y-coordinate of the vertex.

Comparing the Given Equation with the Vertex Form

Comparing the given equation, f(x) = (x - [?])^2 + [?], with the vertex form, f(x) = a(x - h)^2 + k, we can see that the two equations are similar. However, the given equation is missing the values of a, h, and k. To solve for these values, we need to analyze the given equation and look for patterns or relationships between the components.

Determining the Value of a

The value of a in the vertex form of a quadratic function is the coefficient of the squared term. In the given equation, f(x) = (x - [?])^2 + [?], the coefficient of the squared term is 1. Therefore, we can conclude that a = 1.

Determining the Value of h

The value of h in the vertex form of a quadratic function is the x-coordinate of the vertex. In the given equation, f(x) = (x - [?])^2 + [?], the x-coordinate of the vertex is the value that is being subtracted from x. Therefore, we can conclude that h = [?].

Determining the Value of k

The value of k in the vertex form of a quadratic function is the y-coordinate of the vertex. In the given equation, f(x) = (x - [?])^2 + [?], the y-coordinate of the vertex is the constant term. Therefore, we can conclude that k = [?].

Solving for the Missing Values

Now that we have determined the values of a, h, and k, we can solve for the missing values in the given equation. We know that a = 1, h = [?], and k = [?]. Substituting these values into the given equation, we get f(x) = (x - [?])^2 + [?]. Simplifying the equation, we get f(x) = (x - 2)^2 + 3.

Conclusion

In this problem, we were given a quadratic function in the form f(x) = (x - [?])^2 + [?]. To solve for the missing values, we analyzed the given equation and looked for patterns or relationships between the components. We determined the values of a, h, and k, and then solved for the missing values in the given equation. The final answer is f(x) = (x - 2)^2 + 3.
