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

• The vertex tells you the direction of the opening

• The value of "a" tells you the direction of the opening. If a > 0, the graph opens up. If a < 0 the graph opens down.

• All parabolas open upward

• All parabolas open downward

In order to graph a quadratic equation in standard form, the first two steps are to use the equation _____ to find the axis of symmetry (which is the x coordinate of the vertex), and then you can plug that value back into the equation to find the _____.

• -b/2a, y coordinate of the vertex

• (x-h)^2, y-intercept
  

• (x-r1), solution

• ax^2, vertex
