Introduction

In mathematics, a function is a relation between a set of inputs, called the domain, and a set of possible outputs, called the range. The graph of a function is a visual representation of the function, showing the relationship between the input and output values. In this article, we will consider the graph of the function $f(x)=-(2)^\pi+4$ and determine its range.

What is the Range of a Function?

The range of a function is the set of all possible output values. It is the set of all y-values that the function can take. In other words, it is the set of all possible values that the function can output.

Analyzing the Function $f(x)=-(2)^\pi+4$

To determine the range of the function $f(x)=-(2)^\pi+4$ , we need to analyze the function and understand its behavior. The function is a constant function, which means that it has a fixed value for all input values.

Constant Functions

A constant function is a function that always returns the same value, regardless of the input value. In other words, a constant function is a function that has a fixed output value for all input values.

Properties of Constant Functions

Constant functions have several properties that make them easy to work with. Some of the key properties of constant functions include:

Fixed output value: A constant function always returns the same value, regardless of the input value.
No variation: A constant function does not vary with the input value.
No maximum or minimum: A constant function does not have a maximum or minimum value.

Determining the Range of the Function

To determine the range of the function $f(x)=-(2)^\pi+4$ , we need to find the fixed output value of the function. Since the function is a constant function, we can simply evaluate the function at any input value to find the fixed output value.

Evaluating the Function

To evaluate the function $f(x)=-(2)^\pi+4$ , we can substitute any input value into the function. Let's substitute $x=0$ into the function:

$f(0)=-(2)^\pi+4$

Since $2^\pi$ is a constant value, we can simplify the expression:

$f(0)=-4+4$

$f(0)=0$

Conclusion

The range of the function $f(x)=-(2)^\pi+4$ is the set of all possible output values. Since the function is a constant function, the range is a single value, which is the fixed output value of the function. In this case, the range is $\{y \mid y=0\}$ .

Answer

The correct answer is:

A. $\{y \mid -\infty \ \textless \ y \ \textless \ 0\}$

This answer is correct because the range of the function is the set of all possible output values, which is a single value, $0$ . The range is not a set of values that are greater than $0$ , as the function does not vary with the input value.

Final Thoughts

$In conclusion, the range of the function $f(x)=-(2)^\pi+4$ is the set of all possible output values, which is a single value, $0$. The function is a constant function, which means that it has a fixed output value for all input values. Understanding the properties of constant functions is essential in mathematics, as it allows us to work with functions in a more efficient and effective way.<br/> **Q&A: Understanding the Graph of the Function $f(x)=-(2)^\pi+4$**$
