 Axis of Symmetry a line of symmetry for a graph. The two sides of a graph on either side of the axis of symmetry look like mirror images of each other. Symmetry one shape becomes exactly like the other when you translate, rotate, or reflect it Zeros of a quadratic function the roots (x-int­erc­epts) of a parabola Vertex a corner point of a geometric figure/ for a parabola, is the point at which it makes its sharpest turn, halfway between the directrix and focus Intercepts the point at which a curve intersects an axis
