Reflection: Modeling Solving Absolute Value Equations and Inequalities (Day 2 of 2) - Section 2: Graphing Activity


In this lesson, I encouraged my students to try to visualize what the question is asking them to find or to prove. For example:

Is it asking for the x coordinate(s) of the intersection points between two functions, the x and y coordinate(s) of the solution to a system of equations, or just the x- intercept?

I demonstrate in the video below.
