GIZMOS Student Exploration: Absolute Value Equations and Inequalities

tudent Exploration: Absolute Value Equations and Inequalities Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: absolute value, compound inequality, equation, inequality, solution Prior Knowledge Questions (Do these BEFORE using the Gizmo.) The solution of an equation like x + 2 = 5 is the value(s) of x that make the equation true. Gizmo Warm-up You can solve equations by graphing each side, as you did above. In the Absolute Value Equations and Inequalities Gizmo, you will use graphs to find the solutions of equations and inequalities that involve absolute value, the distance a quantity is from 0 on a number line. On the CONTROLS tab in the Gizmo, set a to 1, b to 0, c to 2, and select =. (To quickly set the value of a slider, type the number into the text box to the right of the slider and press Enter.) Notice that each side of |x| = 2 is graphed (y = |x| and y = 2). Reproduction for educational use only. Public sharing or posting prohibited. © 2020 ExploreLearning™ All rights reserved N
