Ashlee -The axis of symmetry is a vertical line that passes through the vertex of this parabola.  Do you know the coordinates of the vertex?  A simple formula for the x-coordinate is:x = -b ÷ 2aThat is the equation for the axis of symmetry!  Just plug in the values for b and a in the equation and you will have your answer.Hope that helps
