Intro to Key Characteristics of Quadratics

A parabola has a vertex at (-3,2). Where is the axis of symmetry?

• y = -2

• x = 3

• x = -3

• y = 2

Is this a max or min?

• max

• min

• cannot be determined

What is another word for zeros?

• y-intercepts

• roots

• vertex

• axis of symmetry

What divides the parabola into 2 perfect halves?

• Axis of Symmetry

• Vertex

• Axis of Doom

• x - intercept

The axis of symmetry is a line that goes through the...

• y-intercept

• any random point

• vertex

•  x-axis or y-axis

What is the vertex?

• (1, -3)

• (-1, 3)

• (3, -1)

• (-3, 1)

What is the quadratic parent function?

• y = mx + b

• y = a(b)^x

• y = x²

• Ax + By = C

What is the vertex of this quadratic equation?

y = 2(x - 2)² + 5

• (-2,5)

• (2,5)

• (5,-2)

• (-5,-2)

What is the max/min value if the vertex is (2,-3)?

• Minimum of 3

• Minimum of -2

• Maximum of 0

• Maximum of 7

What is the arrow pointing at? How can you use this value to determine the minimum/maximum values?

• The arrow is pointing at the y-intercept. The y value of this point is equivalent to the maximum/minimum 

• The arrow is pointing at the vertex. The x value of this point is equivalent to the maximum/minimum

• The arrow is pointing at the solution. The y value of this point is equivalent to the maximum and the x value is equivalent to the minimum

• The arrow is pointing at the vertex. The y value is equivalent to the minimum/maximum
