Is this an open or closed interval?
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).
