Standard form of a quadratic equation

• y=x²
• y=ax²+bx+c
• y=mx+b
• y=x

The graph of a quadratic function is called a

• Parabola
• Vertex
• Axis of Symmetry 
• Vertex Form

A parabola is upside-down when a is:

• negative
• positive
• 0
• infinite

Which best describes the vertex of a parabola?

• Any point on the parabola.
• A point on the x-axis.
• The highest or lowest point of a parabola
• A point on the y-axis.

Name the vertex

• (1,1)

• (0,0)

What is the vertex?

• (2, 4)
• (3, -1)
• (0, 8)
• (4, 2)

What is the discriminant in the Quadratic Formula?
