Graphing Constant Functions

This video tutorial explains how to graph a constant function, specifically p(r) = 5, by plotting points. It covers selecting input values, finding corresponding outputs, and plotting ordered pairs on a Cartesian plane. The tutorial demonstrates that the graph of a constant function is a horizontal line and verifies the graph using a calculator.

What is the main focus of this lesson on graphing functions?

• Graphing logarithmic functions

• Graphing quadratic functions

• Graphing constant functions

• Graphing exponential functions
