Graphing Functions and Analyzing Outputs

This video tutorial covers graphing functions by plotting points. It begins with an introduction to the function s(T) = 4 - 2T, explaining how to select inputs and calculate corresponding outputs. The tutorial demonstrates plotting these points on a Cartesian plane, identifying key intercepts, and verifying the graph using a graphing calculator. The video emphasizes understanding linear functions and their graphical representation.

What is the function rule for s(T) in this lesson?

• s(T) = 2T + 4

• s(T) = 4 - 2T

• s(T) = 2T - 4

• s(T) = 4 + 2T
