How can you tell if a parabola opens upwards or downwards simply by looking at the equation?

• All parabolas open upwards.

• All parabolas open downwards.

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

• It is impossible to determine simply by looking at the equation.

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
