Introduction

In today's digital age, computer systems have become an essential part of our daily lives. From personal computers to servers, the demand for faster and more efficient systems is on the rise. One of the key factors that determine the performance of a computer system is the processor speed. However, as we delve deeper into the world of computer systems, we realize that the cost of a system increases with increased processor speeds. In this article, we will explore the relationship between processor speed and the cost of a computer system.

The Cost Function

The cost $C$ of a system as a function of processor speed is estimated as $C = 11S^2 - 3S + 1100$ , where $S$ is the processor speed in MHz. This quadratic function represents the relationship between the cost of a system and its processor speed. To understand this relationship, let's break down the function into its individual components.

The Quadratic Function

A quadratic function is a polynomial function of degree two, which means that the highest power of the variable is two. In this case, the variable is the processor speed $S$ , and the function is $C = 11S^2 - 3S + 1100$ . The general form of a quadratic function is $f(x) = ax^2 + bx + c$ , where $a$ , $b$ , and $c$ are constants.

The Coefficients of the Quadratic Function

In the given function $C = 11S^2 - 3S + 1100$ , the coefficients are $a = 11$ , $b = -3$ , and $c = 1100$ . The coefficient $a$ represents the rate of change of the function with respect to the variable $S$ . In this case, the coefficient $a$ is positive, indicating that the cost of a system increases as the processor speed increases.

The Vertex of the Quadratic Function

The vertex of a quadratic function is the point at which the function reaches its maximum or minimum value. In this case, the vertex of the function $C = 11S^2 - 3S + 1100$ can be found using the formula $S = -\frac{b}{2a}$ . Plugging in the values of $a$ and $b$ , we get $S = -\frac{-3}{2(11)} = \frac{3}{22}$ .

The Cost at the Vertex

To find the cost at the vertex, we plug in the value of $S$ into the function $C = 11S^2 - 3S + 1100$ . This gives us $C = 11\left(\frac{3}{22}\right)^2 - 3\left(\frac{3}{22}\right) + 1100 = \frac{99}{484} - \frac{9}{22} + 1100 = \frac{99 - 198 + 529200}{484} = \frac{529001}{484}$ .

The Maximum Cost

Since the coefficient $a$ is positive, the function $C = 11S^2 - 3S + 1100$ is an increasing function. This means that the cost of a system increases as the processor speed increases. To find the maximum cost, we need to find the value of $S$ at which the function reaches its maximum value.

The Maximum Value of the Function

To find the maximum value of the function, we can use the fact that the function is increasing. This means that the maximum value of the function occurs at the largest possible value of $S$ . Since the function is increasing, the maximum value of the function occurs at the rightmost point of the graph.

The Rightmost Point of the Graph

To find the rightmost point of the graph, we need to find the value of $S$ at which the function reaches its maximum value. Since the function is increasing, the rightmost point of the graph occurs at the largest possible value of $S$ . In this case, the largest possible value of $S$ is infinity.

The Maximum Cost at Infinity

To find the maximum cost at infinity, we need to find the limit of the function as $S$ approaches infinity. This can be done by plugging in the value of $S$ into the function $C = 11S^2 - 3S + 1100$ and taking the limit as $S$ approaches infinity.

The Limit of the Function

To find the limit of the function, we can use the fact that the function is a quadratic function. This means that the limit of the function as $S$ approaches infinity is equal to the coefficient $a$ multiplied by the limit of $S$ as $S$ approaches infinity.

The Limit of $S$ as $S$ Approaches Infinity

Since the function is a quadratic function, the limit of $S$ as $S$ approaches infinity is equal to infinity.

The Maximum Cost at Infinity

The Limit of the Function as $S$ Approaches Infinity

To find the limit of the function as $S$ approaches infinity, we can use the fact that the function is a quadratic function. This means that the limit of the function as $S$ approaches infinity is equal to the coefficient $a$ multiplied by the limit of $S$ as $S$ approaches infinity.

The Maximum Cost

Since the coefficient $a$ is positive, the limit of the function as $S$ approaches infinity is equal to the coefficient $a$ multiplied by infinity. This means that the maximum cost at infinity is equal to the coefficient $a$ multiplied by infinity.

Conclusion

In conclusion, the cost of a computer system increases with increased processor speeds. The cost function $C = 11S^2 - 3S + 1100$ represents the relationship between the cost of a system and its processor speed. The vertex of the function is the point at which the function reaches its maximum or minimum value. The maximum cost at infinity is equal to the coefficient $a$ multiplied by infinity.
