Introduction

In mathematics, functions play a crucial role in problem-solving and modeling real-world scenarios. A function is a relation between a set of inputs, called the domain, and a set of possible outputs, called the range. In this article, we will explore the concept of a second function, denoted as $$g$$, defined by $$g(x) = -3x + 2$$. We will delve into the properties of this function, its graph, and how it relates to another function, $$f$$.

Defining the Second Function

The second function, $$g$$, is defined as $$g(x) = -3x + 2$$. This means that for any input value of $$x$$, the function $$g$$ will output a value that is $$-3$$ times the input value plus $$2$$. For example, if we input $$x = 2$$, the function $$g$$ will output $$g(2) = -3(2) + 2 = -4$$.

Graphing the Second Function

To visualize the function $$g$$, we can graph it on a coordinate plane. The graph of a linear function is a straight line, and the slope of the line represents the coefficient of the input variable, $$x$$. In this case, the slope is $$-3$$, which means that the line will slope downward from left to right. The y-intercept of the line is $$2$$, which is the value of the function when $$x = 0$$.

Comparing the Two Functions

Now that we have defined and graphed the second function, $$g$$, we can compare it to the first function, $$f$$. We are given that $$f(2)$$ and $$g(2)$$ are related in some way, but we are not told how. We are also asked to select the correct phrase in each drop-down menu to complete the sentence.

Selecting the Correct Phrase

To complete the sentence, we need to understand the relationship between the two functions. Let's start by evaluating $$f(2)$$. We are not given the definition of $$f$$, but we can assume that it is a function that takes an input value and returns an output value. Since we are not given any information about $$f$$, we cannot determine the value of $$f(2)$$.

On the other hand, we can evaluate $$g(2)$$ using the definition of the function $$g$$. We know that $$g(x) = -3x + 2$$, so we can substitute $$x = 2$$ into the equation to get $$g(2) = -3(2) + 2 = -4$$.

Now that we have evaluated both $$f(2)$$ and $$g(2)$$, we can compare the two values. Since we do not know the value of $$f(2)$$, we cannot determine whether it is equal to $$g(2)$$ or not.

Conclusion

In conclusion, we have defined and graphed the second function, $$g$$, and compared it to the first function, $$f$$. We have also evaluated both $$f(2)$$ and $$g(2)$$, but we do not know the value of $$f(2)$$. Therefore, we cannot determine whether $$f(2)$$ is equal to $$g(2)$$ or not.

Introduction

In our previous article, we explored the concept of a second function, denoted as $$g$$, defined by $$g(x) = -3x + 2$$. We delved into the properties of this function, its graph, and how it relates to another function, $$f$$. In this article, we will answer some frequently asked questions about the function $$g$$ and its applications.

Q&A

Q: What is the domain of the function $$g$$?

A: The domain of the function $$g$$ is all real numbers, denoted as $$\mathbb{R}$$. This means that the function $$g$$ can take any real value as input.

Q: What is the range of the function $$g$$?

A: The range of the function $$g$$ is all real numbers less than or equal to $$2$$, denoted as $$(-\infty, 2]$$. This means that the function $$g$$ can output any real value less than or equal to $$2$$.

Q: How do I graph the function $$g$$?

A: To graph the function $$g$$, you can use a coordinate plane and plot the points $$(x, g(x))$$ for various values of $$x$$. You can also use a graphing calculator or software to graph the function.

Q: What is the slope of the function $$g$$?

A: The slope of the function $$g$$ is $$-3$$. This means that the function $$g$$ slopes downward from left to right.

Q: What is the y-intercept of the function $$g$$?

A: The y-intercept of the function $$g$$ is $$2$$. This means that the function $$g$$ intersects the y-axis at the point $$(0, 2)$$.

Q: How do I evaluate the function $$g$$ at a given value of $$x$$?

A: To evaluate the function $$g$$ at a given value of $$x$$, you can substitute the value of $$x$$ into the equation $$g(x) = -3x + 2$$ and simplify.

Q: Can I use the function $$g$$ to model real-world scenarios?

A: Yes, you can use the function $$g$$ to model real-world scenarios. For example, you can use the function $$g$$ to model the cost of producing a product, where the input value $$x$$ represents the number of units produced and the output value $$g(x)$$ represents the total cost.

Q: Can I compare the function $$g$$ to other functions?

A: Yes, you can compare the function $$g$$ to other functions. For example, you can compare the function $$g$$ to the function $$f(x) = 2x - 1$$ to see how they differ.

Q: Can I apply the function $$g$$ to real-world problems?

A: Yes, you can apply the function $$g$$ to real-world problems. For example, you can use the function $$g$$ to calculate the cost of producing a product, where the input value $$x$$ represents the number of units produced and the output value $$g(x)$$ represents the total cost.
