Quadratic Inequalities
Objective: To graph quadratic inequalities with both one and
two variables.
Graph: y = x2 - 3x + 2
What would change if you were
asked to graph y < x2 - 3x + 2?
GRAPH: Remember to shade since........
y ≥ x2 - 7x + 10
y > -3x2 - 6x - 7

GRAPH:
y ≤ -2x2 - 4x + 6
Solve: x2 - 16x + 60 = -3
y = x2 - 8x + 12
How would you solve x2 - 16x + 60 < -3?
Where is x2 - 16x + 63 < 0?
