What is another word for zeros?

• y-intercepts
• roots
• vertex
• axis of symmetry

Use the graph to determine the solutions.

• -1 and -3
• 1 and -3
• 1 and 3
• -1 and 3

What are the green dots called?

• axis of symmetry
• vertex
• parabola
• roots or x-intercepts

What is the vertex of this function?

• (-1,-2)
• (-2,-1)
• (-3,-1)
• (2,1)

What is the green dot on the parabola called?

• maximum
• minumum
• root
• zero

Standard form of a quadratic equation

• y=x²
• y=ax²+bx+c
• y=mx+b
• y=x

The axis of symmetry line passes through which point?

• y-intercept
• any random point
• vertex
• none of these

What is the arrow pointing at? How can you use this value?

• The arrow is pointing at the y-intercept. The x-value is the axis of symmetry and 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 and the y-value is the axis of symmetry
• 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 x-value is the axis of symmetry and the y-value is equivalent to the minimum/maximum

The vertex is... 

• The highest point or the lowest point of the parabola 
• The imaginary line that divides the parabola in half 
• The point where the graph crosses the x-axis
• The point where the graph crosses the y-axis
