What is the Third Iterate of the Function $f(x)=\sqrt{50-3x}$ if $x_0=5.7$?

In this article, we will explore the concept of iterates of a function and how to calculate the third iterate of the function $f(x)=\sqrt{50-3x}$ given the initial value $x_0=5.7$. We will use the concept of recursion to find the third iterate of the function and round the result to three decimal places as needed.

Understanding Iterates of a Function

An iterate of a function is the result of applying the function to a given input value. In other words, if we have a function $f(x)$ and an initial value $x_0$, the first iterate of the function is $f(x_0)$, the second iterate is $f(f(x_0))$, and the third iterate is $f(f(f(x_0)))$. This process can be continued indefinitely.

Calculating the First Iterate

To calculate the first iterate of the function $f(x)=\sqrt{50-3x}$ given the initial value $x_0=5.7$, we substitute $x_0$ into the function:

$$f(x_0)=\sqrt{50-3(5.7)}$$

Using a calculator or a computer program to evaluate the expression, we get:

$$f(x_0)=\sqrt{50-17.1}=\sqrt{32.9}\approx 5.725$$

Calculating the Second Iterate

To calculate the second iterate of the function $f(x)=\sqrt{50-3x}$ given the first iterate $x_1\approx 5.725$, we substitute $x_1$ into the function:

$$f(x_1)=\sqrt{50-3(5.725)}$$

Using a calculator or a computer program to evaluate the expression, we get:

$$f(x_1)=\sqrt{50-17.175}\approx 5.728$$

Calculating the Third Iterate

To calculate the third iterate of the function $f(x)=\sqrt{50-3x}$ given the second iterate $x_2\approx 5.728$, we substitute $x_2$ into the function:

$$f(x_2)=\sqrt{50-3(5.728)}$$

Using a calculator or a computer program to evaluate the expression, we get:

$$f(x_2)=\sqrt{50-17.184}\approx 5.729$$

In this article, we calculated the third iterate of the function $f(x)=\sqrt{50-3x}$ given the initial value $x_0=5.7$. We used the concept of recursion to find the third iterate of the function and rounded the result to three decimal places as needed. The third iterate of the function is approximately $5.729$.

The correct answer is B. $x_3=5.729$.

This problem is a classic example of how to calculate iterates of a function. The concept of iterates is used in many areas of mathematics, including calculus, algebra, and number theory. The problem requires the use of recursion to find the third iterate of the function, which is a fundamental concept in mathematics.

Frequently Asked Questions

In this article, we will answer some frequently asked questions about iterates of a function.

Q: What is an iterate of a function?

A: An iterate of a function is the result of applying the function to a given input value. In other words, if we have a function $f(x)$ and an initial value $x_0$, the first iterate of the function is $f(x_0)$, the second iterate is $f(f(x_0))$, and the third iterate is $f(f(f(x_0)))$. This process can be continued indefinitely.

Q: How do I calculate the first iterate of a function?

A: To calculate the first iterate of a function, you need to substitute the initial value into the function. For example, if we have a function $f(x)=\sqrt{50-3x}$ and an initial value $x_0=5.7$, we substitute $x_0$ into the function:

$$f(x_0)=\sqrt{50-3(5.7)}$$

Using a calculator or a computer program to evaluate the expression, we get:

$$f(x_0)=\sqrt{50-17.1}=\sqrt{32.9}\approx 5.725$$

Q: How do I calculate the second iterate of a function?

A: To calculate the second iterate of a function, you need to substitute the first iterate into the function. For example, if we have a function $f(x)=\sqrt{50-3x}$ and a first iterate $x_1\approx 5.725$, we substitute $x_1$ into the function:

$$f(x_1)=\sqrt{50-3(5.725)}$$

Using a calculator or a computer program to evaluate the expression, we get:

$$f(x_1)=\sqrt{50-17.175}\approx 5.728$$

Q: How do I calculate the third iterate of a function?

A: To calculate the third iterate of a function, you need to substitute the second iterate into the function. For example, if we have a function $f(x)=\sqrt{50-3x}$ and a second iterate $x_2\approx 5.728$, we substitute $x_2$ into the function:

Using a calculator or a computer program to evaluate the expression, we get:

$$f(x_2)=\sqrt{50-17.184}\approx 5.729$$

Q: What is the difference between an iterate and a recursive function?

A: An iterate is the result of applying a function to a given input value multiple times, while a recursive function is a function that calls itself repeatedly until it reaches a base case. In other words, an iterate is a specific value that results from applying a function multiple times, while a recursive function is a function that uses itself to solve a problem.

Q: How do I use iterates in real-world applications?

A: Iterates are used in many real-world applications, including:

• Computer Graphics: Iterates are used to create complex graphics and animations by applying a function multiple times to a given input value.
• Scientific Simulations: Iterates are used to simulate complex systems and processes by applying a function multiple times to a given input value.
• Machine Learning: Iterates are used to train machine learning models by applying a function multiple times to a given input value.
