Graphing Quadratics Transformations

If you describe the transformations of the graph of y=-4\left(x-8\right)^2 from the graph of y=x^2. Which does NOT apply.

• vertically Stretched
  

• Shift right 8 units

• Reflect over x-axis
  

• vertically compressed
  

How can you tell whether a parabola faces up or faces down by looking at the equation?

• The vertex tells you the direction of the opening.

• All parabolas open upward

• The value of the "a" tells you the direction of the opening.

• All parabolas open downward.
