Analyzing Transformations Of Functions H(x)=(2x)^(1/3)+5

Hey everyone! Let's dive into the fascinating world of function transformations, specifically focusing on the function $h(x)=(2x)^{\frac{1}{3}}+5$. We're going to break down how this function is derived from its parent function, $f(x) = x^{\frac{1}{3}}$, and then explore the key properties of the transformed function. So, buckle up and get ready to uncover the secrets behind these mathematical transformations!

The Genesis of h(x) Understanding the Transformation

To truly appreciate the function $h(x)$, we first need to understand its origin. The original function, our starting point, is $f(x) = x^{\frac{1}{3}}$, which represents the cube root of x. Now, the magic happens! This function undergoes a series of transformations to morph into our target function, $h(x)=(2x)^{\frac{1}{3}}+5$. Let's dissect these transformations step by step.

Firstly, we notice that the x inside the cube root is multiplied by 2. This represents a horizontal compression. Imagine squeezing the graph of $f(x)$ horizontally towards the y-axis. The factor of 2 essentially compresses the graph by a factor of $\frac{1}{2}$. In simpler terms, the transformed graph will reach the same y-value as the original graph but at half the x-value.

Next, we see the addition of 5 outside the cube root. This signifies a vertical translation. Think of it as lifting the entire graph of the function upwards along the y-axis. The addition of 5 shifts the graph upwards by 5 units. So, every point on the original graph is moved 5 units higher on the coordinate plane.

In essence, $h(x)$ is created by taking the cube root function, compressing it horizontally by a factor of $\frac{1}{2}$, and then shifting it upwards by 5 units. Understanding these individual transformations is crucial for predicting the behavior and properties of $h(x)$.

Exploring the Properties of h(x) A Deep Dive

Now that we've deciphered the transformations that created $h(x)$, let's delve into its key properties. This is where things get really interesting! We'll be looking at how the function behaves as x changes, its domain and range, and its overall graphical representation. By understanding these properties, we can gain a comprehensive understanding of the function's characteristics.

1. The Behavior of h(x) as x Approaches Infinity and Negative Infinity

Let's start by examining what happens to $h(x)$ as x grows infinitely large (approaches positive infinity) and as x becomes infinitely small (approaches negative infinity). This will give us insights into the function's end behavior.

As x approaches positive infinity, the term $(2x)^{\frac{1}{3}}$ also grows infinitely large, albeit at a slower rate than x itself (due to the cube root). Adding 5 to an infinitely large number doesn't change its infinite nature. Therefore, as x approaches positive infinity, $h(x)$ also approaches positive infinity. In mathematical notation, we write this as:

$$\lim_{x \to \infty} h(x) = \infty$$

Now, let's consider the case where x approaches negative infinity. When x is a large negative number, $(2x)^{\frac{1}{3}}$ becomes a large negative number as well (since the cube root of a negative number is negative). Adding 5 to a large negative number still results in a large negative number. Thus, as x approaches negative infinity, $h(x)$ also approaches negative infinity:

$$\lim_{x \to -\infty} h(x) = -\infty$$

These limits tell us that the graph of $h(x)$ extends indefinitely in both the positive and negative y-directions as x moves further away from zero.

2. The Domain and Range of h(x)

The domain of a function refers to the set of all possible input values (x-values) for which the function is defined. The range, on the other hand, is the set of all possible output values (y-values) that the function can produce.

For $h(x) = (2x)^{\frac{1}{3}} + 5$, let's first consider the cube root part. We know that the cube root function is defined for all real numbers, both positive and negative. This is because you can take the cube root of any real number without encountering any mathematical issues. The multiplication by 2 inside the cube root doesn't change this fact.

Since the cube root part is defined for all real numbers, and adding 5 doesn't introduce any restrictions, the domain of $h(x)$ is all real numbers. We can express this mathematically as:

Domain: $(-\infty, \infty)$

Now, let's determine the range. As we discussed earlier, $h(x)$ approaches both positive and negative infinity as x approaches positive and negative infinity, respectively. Moreover, the cube root function is continuous, meaning it takes on all values between its limits. The vertical translation by 5 units simply shifts the range upwards, but it doesn't change the fact that the function can take on any real value.

Therefore, the range of $h(x)$ is also all real numbers:

Range: $(-\infty, \infty)$

3. The Graphical Representation of h(x)

A visual representation of a function can often provide valuable insights into its behavior. Let's imagine the graph of $h(x)$.

We know that it's a transformed version of the cube root function, which has a characteristic S-shape. The horizontal compression by a factor of $\frac{1}{2}$ will make the graph appear slightly narrower compared to the original cube root function. The vertical translation by 5 units will lift the entire graph upwards by 5 units, shifting its position on the y-axis.

Knowing the end behavior and the domain/range also helps us sketch the graph. We know the graph extends indefinitely in both the positive and negative y-directions. We also know that it's defined for all x-values. Combining this information with the understanding of the transformations, we can visualize a stretched and shifted S-shaped curve.

While we can't draw the graph here, it's highly recommended to use graphing software or a calculator to visualize $h(x)$. This will solidify your understanding of its properties and behavior.

Analyzing the Truth of Statements about h(x) Putting Our Knowledge to the Test

Now that we have a solid understanding of $h(x)$, let's put our knowledge to the test! The original question asks us to evaluate the truthfulness of statements about this function. By carefully analyzing each statement in light of our understanding of the transformations and properties of $h(x)$, we can confidently determine which ones are accurate.

This is where the real fun begins! We'll take each statement, dissect it, and compare it to what we've learned about $h(x)$. Remember, the key is to use our understanding of horizontal compression, vertical translation, domain, range, and end behavior to make informed judgments.

But the above analysis is very crucial to evaluate the options and select the correct answers. You can apply the above knowledge to solve the given problem related to the options.
