Max and Min Parabolas

What is the vertex?

• (0, - 1)
• (0, 0.5)

All Parabolas contain a vertex, when it opens up, this point is called a what?

• Maximum
• Minimum

How do you know if a parabola has a minimum vertex?

• When a is positive there is a minimum
• When a is negative there is a minimum
• When all the numbers in the equation are negative there is a minimum
• When all the numbers in the equation are positive there is a minimum
