Math 2 Notebook/ Assignment Check Unit 4B

(From Notes: Investigating the Graphs of Quadratic Functions)

Fill in the blank: The _____ of a parabola is the highest or lowest point.

• x-intercept

• y-intercept

• vertex

• direction

• axis of symmetry

• (2, 9)

• (-1, 0)

• (5, 0)

• (0, 5)

• (-2, 1)

(From Notes: Finding the Line of Symmetry)

What is the formula for finding the line of symmetry? 

•   a = 1

  b = 4

  c = 3

•   a = x²

  b = 4x

  c = 3

•  a = -1

  b = 4

  c = -3

•   a = -x²

  b = 4x

  c = -3

(From Notes: The Zero Product Property)

• zeros

• solutions

• roots

• maximums

• minimums
