• (1, -4)

• (-2, 5)

• {-1, 3}

What is the green dashed line called?

• roots or x-intercepts
• parabola
• axis of symmetry
• y intercept

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

• y = -2
• x = 3
• x = -3
• y = 2

Write the factored form of the polynomial with roots x=-2. x=5, x=2/3

• y=(x-2)(x+5)(3x+2)

• y=(x-2)(x+5)(2x+3)

• y=(x+2)(x-5)(2x-3)

• y=(x+2)(x-5)(3x-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

• No Solution

Solve using the quadratic formula...
