What do we call the graph of a quadratic function?

• parabola
• linear
• cubic
• sinusoidal

What is the vertex of this function?

• (0, -3)

• (1, -4)

• (-2, 5)

• {-1, 3}

What is the axis of symmetry for the following equation?

y=4x²-8x+9

• x=-8

• x=1

• x=-1

• x=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 maximum/minimum of a parabola called?

• vertex
• point
• top
• bottom
