Characteristics of Quadratics from a Graph

What is the significance of the ordered pair (0, -2) to the graph?

• It is the vertex

• It is an x-intercept

• It is the y-intercept

• It is the axis of symmetry

What are the coordinates of the vertex, and is it a maximum or minimum?

• (-1, 4); Maximum

• (-1, 4); Minimum

• (4, -1); Maximum

• (4, -1); Minimum

What do we call the highest or lowest point of a quadratic?

• parabola

• vertex

• graph

• point

How many zeros does this parabola have? 

• 3

• 2

• 0

• 1

• x = -4

• (-3, 0)

• (-1, -4)

• (0, -3)

• x = -1

• (-4, -1)

• (5, 0)

y=4x^2 Select the 2 correct descriptions.

• Opens up

• Opens down

• Narrower than parent graph (stretch)

• Wider than parent graph (compression)

Vertex: ​ (a)   Y-intercept: ​ (b)   Axis of Symmetry: ​ (c)   Max or min: ​ (d)   Range:​ (e)
