Parabolas Basics

What is the correct name for the transformation from y=x²   to  y = -x²?

• Reflection
• Translation
• Dilation
• Transformer

When you subtract a constant from y=x²  what happens to the graph?  For example, y = x² - 2

• Graph moves UP

• Graph moves to the RIGHT

• Graph moves DOWN

• Graph moves to the LEFT

What happens to the parabola when the 'a' value is greater than 1?   For example,  y = 3x²

• Graph moves UP

• Graph gets WIDER

• Graph moves DOWN

• Graph gets NARROWER

The axis of symmetry line passes through which point?

• y-intercept
• any random point
• vertex
• symmetrical point for the vertex

The graph of a quadratic function is called a

• Parabola
• Vertex
• Axis of Symmetry 
• Vertex Form

Use the graph to determine the solutions.

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

What are the zeros?

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

Name the roots?

• 0
• 4
• 2
• 0 and 4

Transformation:  Which describes the transformation of the graph f(x) = x² to the new graph of g(x) = 5x² ?

• The graph of g(x) is wider.
• The graph of g(x) is narrower
• The graph of g(x) reflects
• The graph of g(x) is to the right
