This equation is quadratic (meaning it has a squared term) so its graph is a parabola, a U shape. The axis of symmetry of a parabola is the "mirror line" down the middle of the U. Since the axis of symmetry is a line, your answer should be in the form of an equation of a line. Since this parabola opens upward (as opposed to left or right) the axis of symmetry will be a vertical line, so its equation will look something like x=3 or x= -1. The exact value you will have to determine, but it will go through the parabola's vertex (lowest point).
