Combining transformation of graphs with solutions to absolute value inequalities
Ryan Fox · Scholarship & Creative Works - Digital UNC a service of University Libraries (University of Northern Colorado) · 2020
I present how transformations can be applied to support students’ solving linear inequalities involving absolute value. In particular, the horizontal dilations/compressions and translations of graphical representations of distances from zero along a number line are important tools to emphasize a visual representation of the solutions to absolute value inequalities.
