Exploring the Behavior of the Function F(x) as x Approaches 2

Understanding the Function F(x)

The given function is $$F(x)=\frac{1}{x-2}$$. This is a rational function, where the numerator is a constant (1) and the denominator is a linear expression (x - 2). The behavior of this function can be understood by analyzing its components.

Analyzing the Denominator

The denominator of the function is (x - 2). When x is close to 2, the value of the denominator approaches 0. This is because as x gets closer to 2, the difference between x and 2 becomes smaller and smaller.

The Impact of a Small Denominator

When the denominator of a fraction is small, the value of the fraction becomes large. This is because the numerator is being divided by a small number, resulting in a large quotient. In the case of the function F(x), as the denominator (x - 2) approaches 0, the value of F(x) becomes very large.

Exploring the Options

Now that we understand the behavior of the function F(x) as x approaches 2, let's examine the options provided:

A. 10,000 B. 0.01 C. -0.01 D. 2

Option A: 10,000

As x approaches 2, the value of F(x) becomes very large. In fact, it becomes infinitely large. This is because the denominator (x - 2) approaches 0, resulting in a fraction with an infinitely large quotient. Therefore, option A (10,000) is a possible value of F(x) when x is close to 2.

Option B: 0.01

As x approaches 2, the value of F(x) becomes very large, not small. Therefore, option B (0.01) is not a possible value of F(x) when x is close to 2.

Option C: -0.01

Similarly, as x approaches 2, the value of F(x) becomes very large, not small. Therefore, option C (-0.01) is not a possible value of F(x) when x is close to 2.

Option D: 2

As x approaches 2, the value of F(x) becomes very large, not 2. Therefore, option D (2) is not a possible value of F(x) when x is close to 2.

Conclusion

Based on our analysis, the correct answer is option A (10,000). This is because as x approaches 2, the value of F(x) becomes very large, and 10,000 is a possible value of F(x) in this scenario.

Additional Insights

It's worth noting that the function F(x) is not defined at x = 2, because the denominator (x - 2) would be equal to 0, resulting in an undefined fraction. However, as x approaches 2, the value of F(x) becomes very large, as we've discussed earlier.

Graphical Representation

To visualize the behavior of the function F(x) as x approaches 2, we can plot the graph of the function. The graph will show that as x approaches 2, the value of F(x) becomes very large, and the graph will approach the vertical asymptote at x = 2.

Real-World Applications

The behavior of the function F(x) as x approaches 2 has real-world applications in various fields, such as physics, engineering, and economics. For example, in physics, the function F(x) can be used to model the behavior of a system with a singularity at x = 2. In engineering, the function F(x) can be used to design systems that approach a singularity at x = 2. In economics, the function F(x) can be used to model the behavior of a system with a singularity at x = 2.

Conclusion

In conclusion, the function F(x) = 1/(x - 2) has a very large value as x approaches 2. This is because the denominator (x - 2) approaches 0, resulting in a fraction with an infinitely large quotient. Therefore, option A (10,000) is a possible value of F(x) when x is close to 2.
