Poll

For the three types of quadratic equations we have graphed so far, which do you feel is the most difficult?

• Vertex Form

  $$y=a\left(x-h\right)^2+k$$

• Standard Form

  $$y=ax^2+bx+c$$

• Factored Form

  $$y=a\left(x-p\right)\left(x-q\right)$$

• I'm feeling comfortable with all three types.
