1.4 Solving Absolute Inequalities (Due 10/18/24)

Last updated 12 months ago
76 questions
Essential Question:How can we solve and interpret absolute value inequalities to find the range of possible solutions?

Learning Target: Students will be able to solve absolute value inequalities and represent their solutions on a number line, understanding how the inequality affects the direction and type of solution set (e.g., union of intervals or a bounded interval).
