INTRO:
Mathematical equations are used to represent and describe the behavior of a graph. Knowing which equation corresponds to a given graph is an important skill for anyone to have, especially if they are studying mathematics or engineering. In this article, we will discuss how to identify which equation represents a given graphed function.
Understanding the Graph
When trying to determine which equation represents a given graph, it is important to understand the different features of the graph. A graph generally consists of two axes, the x-axis and the y-axis. The x-axis is the horizontal axis, and the y-axis is the vertical axis. The x-axis represents the independent variable while the y-axis represents the dependent variable. The graph also contains a line or curve that connects the points on the graph. This line or curve is called the function, and it represents the relationship between the x and y variables.
Identifying the Equation
Once you understand the features of the graph, you can then identify the equation that represents the graphed function. The equation will generally be in the form of an equation with two variables, such as y = mx + b. The m in the equation represents the slope of the graph, and the b represents the y-intercept. The slope and y-intercept are determined by the points on the graph. By analyzing the points on the graph, you can determine the slope and y-intercept and then solve for the equation.
Once you have the equation, you can then use it to determine the behavior of the graph. You can also use the equation to solve for x or y values given certain conditions.
