  1. Review/Preview (Unit 1A) #5

  2. Let’s review graphing linear inequalities

  3. Boundary lines y x y x If the inequality is ≤ or ≥ , the boundary line is solid;its points are solutions. Example: The boundary line of the solution set ofy≤ 3x - 2 is solid. If the inequality is < or >, the boundary line is dotted; its points are not solutions. Example: The boundary line of the solution set ofy< - x + 2is dotted.

  4. Quadratic InequalitiesEQ: How do we determine solutions of and graph quadratic inequalities? M2 Unit 1B: Day 6 M2 Unit 1B: Day 6

  5. Determine if the point is a solution to the quadratic inequality 3 < -11 (2, 3) is NOT a solution!

  6. Determine if the point is a solution to the quadratic inequality (0,-2) is a solution!

  7. Quadratic Inequalities Dashed parabola Shade below vertex Solid parabola Shade below vertex Dashed parabola Shade above vertex Solid parabola Shade above vertex

  8. Steps to graph quadratic inequalities • Determine if dashed or solid • Graph parabola • Shade above or below the parabola (vertex)

  9. Graph the quadratic using the axis of symmetry and vertex. Vertex: Y-intercept: One more point: Since ≥ the parabola is solid! Since ≥ shade inside!

  10. Graph the quadratic using the axis of symmetry and vertex. Vertex: Y-intercept: One more point: Since > the parabola is dashed! Since > shade inside!

  11. Graph the quadratic using the axis of symmetry and vertex. Vertex: Y-intercept: One more point: Since < the parabola is dashed! Since < shade outside!

  12. Graph the quadratic using the axis of symmetry and vertex. Vertex: Y-intercept: One more point: Since ≤ the parabola is solid! Since ≤ shade outside!
