Quadratic Function Graph Characteristics

Quadratic equations take the shape of a _______ when graphed.

• parabola

• straight line

• snaked line

• elliptical

What is the domain and the range for the graph?

• Domain : -2 ≤ x ≤ 2
  Range : 0 ≤ y ≤ 4

• Domain : 0 ≤ x ≤ 4
  Range : -2 ≤ y ≤ 2

• Domain : All real #s
  Range : y ≤ 4

• Domain : -2 ≤ x ≤ 2
  Range : y ≤ 4

Using your calculator, graph y = -3x² + 6x - 5 and identify the max or min.

• Max: (1, -2)

• Min: (1, -2)

• Max: (-2, 1)

• Min: (-2, 1)
