A3 1.7a Interval Notation, Intersection and Union of Intervals, Solving One Variable Inequalities Homework: p. 195-196 1-45 odd

Interval Notation Solve and report answer graphically. Interval Notation:Graph:

Using Interval Notation Express each interval in set-builder notation and graph.

Intersections and Unions of Intervals Use graphs to find the solution set:

Solving Linear Inequalities in One Variable Manage the equation as an equality, then bring in the inequality signs. Remember: if you multiply or divide by a negative number while solving, the inequality sign switches!

Guided Practice Solve. Report answers in interval notation.

Inequalities with unusual solution sets…

Whiteboard Problems: Express the interval notation in set-builder notation: Solve: Solve. Express answer in interval notation.
