Quadratic Functions

The graph of a quadratic function is called a

• Parabola
• Vertex
• Axis of Symmetry 
• Vertex Form

What divides the parabola into 2 perfect halves?

• Axis of Symmetry
• Vertex
• Axis of Doom
• x - intercept

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

• parabola
• vertex
• graph
• point

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

What is the vertex?

• (2, 4)
• (3, -1)
• (0, 8)
• (4, 2)

Does this graph have a maximum or minimum value?

• maximum
• minimum
• neither
• both

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

• max/ opens down
• min/ opens up
• max/ opens up
• min/ opens down

What are the x- intercepts?

• x= 0 and x= -4
• x= 0 and x= 4
• y= 0
• x= 2

The axis of symmetry of this parabola is...

• y = 4
• y = -4
• x = 4
• x = -4

What direction is the following equation opening?
y=-3x²-7x+8

• Up
• Down
• Left
• Right
