Introduction to Functions G and H
In mathematics, functions are a fundamental concept that helps us describe the relationship between variables. In this article, we will explore two functions, G and H, and analyze their behavior based on the given equations and tables. Function G is represented by the equation y = 8x - 1, while function H is represented by a table with x and y values.
Function G: y = 8x - 1
Function G is a linear function that can be represented by the equation y = 8x - 1. This equation tells us that for every value of x, the corresponding value of y is obtained by multiplying x by 8 and then subtracting 1. For example, if x = 1, then y = 8(1) - 1 = 7.
Graphing Function G
To visualize the behavior of function G, we can graph it on a coordinate plane. The graph of function G will be a straight line with a slope of 8 and a y-intercept of -1. The graph will pass through the points (0, -1) and (1, 7).
Function H: Analyzing the Table
Function H is represented by a table with x and y values. The table is as follows:
| x | y |
|---|---|
| -2 | -1 |
| 0 | 0 |
| 2 | 1 |
Analyzing the Table
From the table, we can see that function H has three distinct points: (-2, -1), (0, 0), and (2, 1). We can use these points to analyze the behavior of function H.
Finding the Equation of Function H
To find the equation of function H, we can use the points in the table to determine the slope and y-intercept of the function. The slope of function H can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)
Using the points (-2, -1) and (2, 1), we can calculate the slope as follows:
m = (1 - (-1)) / (2 - (-2)) = 2 / 4 = 1/2
The y-intercept of function H can be found by substituting x = 0 and y = 0 into the equation. This gives us:
0 = m(0) + b 0 = b b = 0
Therefore, the equation of function H is y = (1/2)x.
Comparing Functions G and H
Now that we have analyzed functions G and H, we can compare their behavior. Function G is a linear function with a slope of 8 and a y-intercept of -1, while function H is a linear function with a slope of 1/2 and a y-intercept of 0.
Key Differences
There are several key differences between functions G and H. The first difference is the slope of the functions. Function G has a slope of 8, while function H has a slope of 1/2. This means that function G will increase more rapidly than function H.
The second difference is the y-intercept of the functions. Function G has a y-intercept of -1, while function H has a y-intercept of 0. This means that function G will intersect the y-axis at a point below the origin, while function H will intersect the y-axis at the origin.
Conclusion
In conclusion, functions G and H are two distinct linear functions that can be represented by different equations and tables. Function G is a linear function with a slope of 8 and a y-intercept of -1, while function H is a linear function with a slope of 1/2 and a y-intercept of 0. By analyzing the behavior of these functions, we can gain a deeper understanding of the relationships between variables and how they can be represented mathematically.
