Introduction

In the realm of mathematics, rational functions play a crucial role in modeling real-world phenomena. These functions are characterized by their ability to exhibit various types of behavior, including vertical asymptotes. In this article, we will delve into the concept of vertical asymptotes in rational functions, with a specific focus on the function $F(x) = \frac{3x}{4x - 4}$ . Our primary objective is to determine the value of $x$ at which the graph of this function has a vertical asymptote.

What are Vertical Asymptotes?

A vertical asymptote is a vertical line that a function approaches but never touches. In other words, it is a line that the function gets arbitrarily close to, but never actually intersects. Vertical asymptotes are an essential concept in mathematics, as they provide valuable information about the behavior of a function.

Characteristics of Vertical Asymptotes

Vertical asymptotes are typically associated with rational functions that have a denominator of zero. When the denominator is zero, the function becomes undefined, resulting in a vertical asymptote. The value of $x$ at which the denominator is zero is known as the asymptote's location.

**The Function $F(x) = \frac{3x}{4x - 4}$

The given function $F(x) = \frac{3x}{4x - 4}$ is a rational function with a numerator of $3x$ and a denominator of $4x - 4$ . To determine the value of $x$ at which this function has a vertical asymptote, we need to find the value of $x$ that makes the denominator zero.

Finding the Vertical Asymptote

To find the vertical asymptote, we set the denominator equal to zero and solve for $x$ :

4x - 4 = 0

Solving for $x$ , we get:

4x = 4

x = 1

Therefore, the value of $x$ at which the graph of the function $F(x) = \frac{3x}{4x - 4}$ has a vertical asymptote is $x = 1$ .

Conclusion

In conclusion, the graph of the function $F(x) = \frac{3x}{4x - 4}$ has a vertical asymptote at $x = 1$ . This value of $x$ makes the denominator zero, resulting in a vertical asymptote. Understanding vertical asymptotes is crucial in mathematics, as they provide valuable information about the behavior of a function.

The correct answer is:

Introduction

In our previous article, we explored the concept of vertical asymptotes in rational functions, with a specific focus on the function $F(x) = \frac{3x}{4x - 4}$ . We determined that the graph of this function has a vertical asymptote at $x = 1$ .

Q&A

Q: What is a vertical asymptote?

A: A vertical asymptote is a vertical line that a function approaches but never touches. It is a line that the function gets arbitrarily close to, but never actually intersects.

Q: What is the relationship between vertical asymptotes and rational functions?

A: Vertical asymptotes are typically associated with rational functions that have a denominator of zero. When the denominator is zero, the function becomes undefined, resulting in a vertical asymptote.

Q: How do you find the vertical asymptote of a rational function?

A: To find the vertical asymptote, you need to set the denominator equal to zero and solve for $x$ . The value of $x$ that makes the denominator zero is the location of the vertical asymptote.

Q: What is the significance of vertical asymptotes in mathematics?

A: Vertical asymptotes provide valuable information about the behavior of a function. They help us understand the function's limitations and how it behaves as it approaches certain values.

Q: Can a function have multiple vertical asymptotes?

A: Yes, a function can have multiple vertical asymptotes. This occurs when the function has multiple values of $x$ that make the denominator zero.

Q: How do you determine the type of vertical asymptote (e.g., removable, non-removable)?

A: To determine the type of vertical asymptote, you need to examine the behavior of the function as it approaches the asymptote. If the function approaches a finite value, it is a removable asymptote. If the function approaches infinity, it is a non-removable asymptote.

Q: Can a function have a vertical asymptote at $x = 0$ ?

A: Yes, a function can have a vertical asymptote at $x = 0$ . This occurs when the function has a denominator of the form $x - 0$ , which becomes zero when $x = 0$ .

Q: How do you graph a function with a vertical asymptote?

A: To graph a function with a vertical asymptote, you need to draw a vertical line at the location of the asymptote. The function will approach this line but never touch it.

Q: Can a function have a vertical asymptote at a complex number?

A: Yes, a function can have a vertical asymptote at a complex number. This occurs when the function has a denominator that becomes zero at a complex value of $x$ .

Q: How do you find the vertical asymptote of a rational function with a quadratic denominator?

A: To find the vertical asymptote of a rational function with a quadratic denominator, you need to factor the denominator and set each factor equal to zero. The values of $x$ that make each factor zero are the locations of the vertical asymptotes.

Q: Can a function have a vertical asymptote at a point where the numerator is also zero?

A: Yes, a function can have a vertical asymptote at a point where the numerator is also zero. This occurs when the function has a common factor in the numerator and denominator.

Q: How do you determine the type of vertical asymptote (e.g., removable, non-removable) for a rational function with a quadratic denominator?
