Test Friday on the parabola
(A)Test will cover graphing a parabola and labeling vertex, focus, A.O.S.,
Directrix and any intercepts. ( this will include completing the square)
(B)Test will cover given information give back equation.
To find x-intercepts let y = 0 and solve
Find Vertex, A.O.S., Focus, Dir: and any intercepts
9) y = -x2 + 4x - 2
To find y -intercepts let x = 0 and solve
