Presentation transcript:

MM2A4. Students will solve quadratic equations and inequalities in one variable. d. Solve quadratic inequalities both graphically and algebraically, and describe the solutions using linear inequalities.

MM2A4d MM2A4d Solve quadratic inequalities both graphically and algebraically, and describe the solutions using linear inequalities. To graph a quadratic INEQUALITY, follow the exact same steps you would to graph a quadratic equation!!

MM2A4d MM2A4d Solve quadratic inequalities both graphically and algebraically, and describe the solutions using linear inequalities. The parabola will have a: Solid boundary: if standard form has ≥ or ≤. Broken boundary: if standard form has > or <.

MM2A4d MM2A4d Solve quadratic inequalities both graphically and algebraically, and describe the solutions using linear inequalities. SHADE: Above the boundary (vertex): if standard form has > or ≥. Below the boundary (vertex): if standard form has < or ≤.
