quadratics

Which answer choice describes  y = -3x² +7x - 2 accurately?

• opens up with a maximum
• opens up with a minimum
• opens down with a maximum
• opens down with a minimum 

Does the following quadratic equation have a maximum or minimum value? How can you tell?
y=x²+2x-3

• Minimum value, because the a value is positive
• Maximum value, because the b value is positive
• Maximum value, because the a value is positive
• Minimum value, because the c value is negative

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

• 16
• 8
• -8
• -24

Solve  by factoring
x² + 13x + 12 = 0

• x = -12, -1
• x = 12, 1
• x = 13, 1
• x = -13, -1

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

• 16

• -8

• 8

• -24

Does this graph have a maximum or minimum?

• Minimum
• Maximum

What is the axis of symmetry of:y=2x²-4x+9

• x = 1
• x = -1
• x = -2
• x = 4

What is the y-intercept of: y=7x²+2x -1

• (0, 1)
• (0, -1)
• (1, 0)
• (-1, 0)

What are the zeros?

• x= 0 and x= -4
• x= 0 and x= 4
• y= 0
• x= 2

Solve
a² + 2a - 24 = 0

• a = -6, 4
• a = 6, -4
• a = 12, -2
• a = 8, -3
