What is the maximum/minimum of a parabola called?

• vertex

• point

• top

• bottom

What is the most correct way to find the y-intercept of any function?

• Look at the last number

• Plug in zero for x

• You have to do it a different way for every equation

• Add all of the coefficients together

Which is the vertex of y = x²+ 16x + 71 ?

• V(-8, 7)

• V(-8, 3)

• V(8, 10)

• V(16, -2)

How can you tell whether a parabola opens up or opens down by looking at the equation?

• The vertex tells you the direction of the opening

• The value of "a" tells you the direction of the opening.

• All parabolas open upward

• All parabolas open downward
