One-Variable Quadratic Equation Problem-Solving

Does this graph in the back have maximum or minimum value?

• maximum
• minimum
• neither
• both

What is the axis of symmetry for the following equation?
y=4x²-8x+9

• x=-8
• x=1
• x=-1
• x=2

What is the y intercept for the equation:
y = -8x² + 3x - 7

• (0, -8)
• (0, 3)
• (0, 7)
• (0, -7)

Solve:
2x² - 9x = 35

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

Solve:
4x² = -4x -1

• x = -½
• x = -2
• x = 0

• -3, 4
• 3, 4
• -4, -3
• -3

A parabola has a vertex at (-3,2). Where is the axis of symmetry?

• y = -2
• x = 3
• x = -3
• y = 2

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

What is the axis of symmetry?

• the slope of the graph
• the dividing line for a parabola
• a way to spin my pencil
• the x-axis

Factor:  x² + 13x + 30

• (x + 3)(x + 10)
• (x + 5)(x + 6)
• (x + 2)(x + 15)
• (x + 1)(x + 30)
