• (3,8)
• (-3,-8)
• (-3,8)
• (3,-8)

What is the domain and range of the given parabola:
 y=6(x-4)²-1?

• Domain: all real numbers
  Range: y≥-1
• Domain: x≥-1
  Range: all real numbers
• Domain: all real numbers
  Range: y ≤-1
• Domain: x≤-1
  Range: all real numbers

The graph of a quadratic function is called a

• Parabola
• Vertex
• Axis of Symmetry 
• Vertex Form

• √3
• ±√3
• -3
• No real solution

• ±23.25
• ±5
• ±25
• No real solution

• ± 1
• ± 4/3
• ± 3/4
• No real solution

Convert x²+6x+9 to factored form and identify the solution.

• (x+3)(x+3); x=-3
• (x+4)(x+5); x=-4, -5
• (x-3)(x-3); x=3
• Not factorable

Which method should you use to solve this equation?
3x² - 8x + 15 = 0

• Solve Symbolically (SADMEP)
• Zero Product Property
• Quadratic Formula

Identify the a, b and c values for this equation:
3x² - 8x + 15 = 0

• a=3, b=8, c=0
• a=3, b=-8, c=15
• a=3, b=8, c=15

What should you do first in solving this equation?
x² + 6x - 13 = 3

• Get factored form
• Write down: a=1, b=6, c=-13
• Make it equal 0 by subtracting 3 on each side
• Type it all in a calculator.
