Algebra 1 - Graphing and quadratic formula

Is the graph shown above a max or min?

• Maximum

• Minimum

Is the graph shown above a max or min?

• Minimum

• Maximum

What is the vertex of the graph shown above?

• (7,6)

• (-1,2)

• (2,-1)

• (5,0)

What is the vertex?

• (2, 4)
• (3, -1)
• (0, 8)
• (4, 2)

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3

• a = 4, b = -8, c = 3
• a = 4, b =-8, c =-3
• a = 4, b = 8, c = 3
• a = 4, b = 8, c = -3

What is this formula?

• This is the speed of light formula.
• This is the quadratic formula.
• This is the zero product property.
• This is scary.

Identify the 'b' value: y = 16x² -8x -24

• 16
• -8
• 8
• -24

Factor: x² – 5x – 24

• (x - 5)(x + 19)
• (x - 8)(x + 3)
• (x - 3)(x + 8)
• (x - 19)(x + 5)

Solve using the quadratic formula.
2x² - 9x - 35 = 0

• x = 7/2, x = -6
• x = -5/2, x =5
• x = -3/7, x =6
• x = -5/2, x = 7

Solve using the Quadratic Formula:

2x² + x - 4 = 0

• x = -¼ and x = -2

• x = 1.19 and x = -1.69

• x = 8 and x = -4

• x = 1.69 and x = 1.20
