Graph functions are mathematical expressions that are used to represent the relationship between two variables. They are typically represented visually on a graph, with one variable plotted on the x-axis and the other on the y-axis.
Graph functions have several key features that help us understand the relationship between the two variables being represented. These features include the slope, intercepts, symmetry, and domain and range.
Graph functions are used in a variety of fields, including mathematics, science, economics, and engineering. They are particularly useful for analyzing data and making predictions based on that data.
A linear graph function represents a relationship between two variables that can be expressed as a straight line, while a non-linear graph function represents a relationship that cannot be expressed as a straight line. Non-linear functions can take on various shapes, such as curves, parabolas, and exponential growth or decay.
To plot a graph function, you will need to identify the variables involved and the relationship between them. Then, you can choose a suitable scale for the x-axis and y-axis, plot points on the graph, and connect them to create a visual representation of the function.
