Graph each equation. ƒ(x) = 3

Key Concepts

Constant Functions

A constant function is a type of function where the output value remains the same regardless of the input value. In the case of ƒ(x) = 3, the function outputs the value 3 for every x in its domain. This results in a horizontal line on the graph, indicating that no matter what x-value is chosen, the y-value will always be 3.

Graphing Functions

Graphing functions involves plotting points on a coordinate plane to visually represent the relationship between the input (x) and output (y) values. For the function ƒ(x) = 3, you would plot points such as (0, 3), (1, 3), and (-1, 3), all of which lie on the same horizontal line. Understanding how to graph functions is essential for visualizing their behavior.

Coordinate Plane

The coordinate plane is a two-dimensional surface defined by a horizontal axis (x-axis) and a vertical axis (y-axis). Each point on the plane is represented by an ordered pair (x, y). In graphing the function ƒ(x) = 3, recognizing how to locate points on the coordinate plane is crucial, as it allows for the accurate representation of the function's output across different input values.
