Quadratic Function Understanding

The graph of a quadratic function is called a

• Parabola

• Vertex

• Axis of Symmetry

• Thor's hammer

What is the green dot on the parabola called?

• vertex

• line of symmetry

• solution

• Loki's staff

What is the axis of symmetry?

• the slope of the graph

• the dividing line for a parabola

• a way to spin my pencil

• always the y-axis

Does the quadratic have a max/min vertex, and does the parabola open up/down?

• max/ opens down

• min/ opens up

• max/ opens up

• min/ opens down

Does this parabola have a maximum or minimum and does it open up or down?

• Maximum; up

• Minimum; down

• Minimum; up

Does

y = -4x²

have a maximum or minimum value? Does it open up or down?

• maximum; down

• minimum; up

• minimum; down

• maximum; up

Does

y = 4x²

have a maximum or minimum value? Does it open up or down?

• maximum; down

• minimum; up

• minimum; down

• maximum; up

The line of symmetry of this parabola is...

• x = 1

• x = 0

• x = -12.5, -4

• x = 4

Does this parabola have a minimum or maximum and what is its value? (Hint: the value is related to the range)

• minimum: 2

• maximum: 2

• minimum: 5

• maximum: 5

What transformations happened to the parent function?

• Translation right and reflection over the x-axis

• Translation left and reflection over the x-axis

• Translation right

• Translation left
