What is the maximum/minimum of a parabola called?

• vertex

• point

• top

• bottom

What is the vertex?

What is the vertex of a parabola?

• The max or min

• The point the line of symmetry goes through

• The point that is the same distance from both x-ints

• All of the above

What is the relationship between the vertex and the x-intercepts?

• the vertex is in the middle

• the vertex is closer to one of them

• the vertex is the same distance from both points

• There is no special relationship

What is the standard form of the quadratic equation, 5x² = 3x - 4

• 5x² + 3x + 4 = 0

• 5x² - 3x + 4 = 0

• 5x² + 3x - 4 = 0

• 5x² - 3x - 4 = 0
