Review/Preview (Unit 1A) #5

Let’s review graphing linear inequalities

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

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

Determine if the point is a solution to the quadratic inequality

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

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

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

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

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

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