Questions And Answers
Parabola's Standard Form (x2): focus (h,k+c)
Parabola's Standard Form (x2): axis of symmetry (x=h)
Parabola's Standard Form (x2): directrix (y=k-c)
Axis of Symmetry A line that cuts through the middle of the parabola, intersecting at the
vertex
Vertex Parabola's lowest point if graphs points up, highest point if graph points down
The Value C The distance from the vertex to both the focus and directrix (measured along
axis of symmetry); will always be POSITIVE
The Value A in the Standard Form +/- (1/(4c))
