Understanding Constant Functions and Graphing

The video tutorial explains how to identify the slope and intercepts of the equation f(x) = 3, a constant function. It demonstrates rewriting the equation in slope-intercept form, identifying the slope as zero and the vertical intercept as (0, 3). The tutorial also covers graphing the function as a horizontal line and using a table of values to confirm the graph. It concludes with tips on recognizing constant functions and their properties.
