The Tables Represent the Functions $f(x)$ and $g(x)$ : A Mathematical Analysis

In mathematics, functions are a fundamental concept that plays a crucial role in various branches of mathematics, including algebra, calculus, and analysis. 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 analyze two functions, $f(x)$ and $g(x)$ , represented by the tables below.

Function $f(x)$

$x$	$f(x)$
-3	-5
-2	-3
-1	-1
0	1
1	3
2	5

Function $g(x)$

$x$	$g(x)$
-3	-3
-2	-1
-1	1
0	3
1	5
2	7

Analyzing the Functions

From the tables, we can observe that both functions have a domain of $x = -3, -2, -1, 0, 1, 2$ . However, the range of the functions is different. The range of $f(x)$ is $-5, -3, -1, 1, 3, 5$ , while the range of $g(x)$ is $-3, -1, 1, 3, 5, 7$ .

Determining the Type of Functions

To determine the type of functions, we need to analyze the behavior of the functions as $x$ varies. From the tables, we can observe that both functions are increasing functions, meaning that as $x$ increases, $f(x)$ and $g(x)$ also increase.

Finding the Domain and Range of the Functions

The domain of a function is the set of all possible input values, while the range is the set of all possible output values. From the tables, we can see that the domain of both functions is $x = -3, -2, -1, 0, 1, 2$ . However, the range of the functions is different.

Finding the Inverse of the Functions

The inverse of a function is a function that undoes the action of the original function. In other words, if $f(x)$ is a function, then its inverse is a function $f^{-1}(x)$ such that $f(f^{-1}(x)) = x$ and $f^{-1}(f(x)) = x$ .

Finding the Composition of the Functions

The composition of two functions is a function that is obtained by applying one function to the output of the other function. In other words, if $f(x)$ and $g(x)$ are two functions, then their composition is a function $f \circ g(x) = f(g(x))$ .

In conclusion, we have analyzed two functions, $f(x)$ and $g(x)$ , represented by the tables above. We have determined the type of functions, found the domain and range of the functions, and found the inverse and composition of the functions. These concepts are essential in mathematics and have numerous applications in various fields, including science, engineering, and economics.

$g(x)$	$x = -3, -2, -1, 0, 1, 2$	$-3, -1, 1, 3, 5, 7$	Increasing	$g^{-1}(x) = \frac{x+3}{2}$	$g \circ f(x) = g(f(x)) = \frac{5x+3}{2}$

Q: Are the functions increasing or decreasing?

A: Both functions are increasing functions, meaning that as $x$ increases, $f(x)$ and $g(x)$ also increase.

Q: What is the inverse of the functions?

A: The inverse of $f(x)$ is $f^{-1}(x) = \frac{x+5}{2}$ , while the inverse of $g(x)$ is $g^{-1}(x) = \frac{x+3}{2}$ .
