Parabolas State whether the parabola will open up/down OR right/left. (y-k)2 = 4p(x-h) Regardless of the direction the parabola opens the vertex is always in the form ( , ). (x-h)2 = 4p(y-k) right/left ? up/down ? focus: Vertex: directrix: Opens: p = ( x2 = 8y ( , , = ) ) focus: Vertex: directrix: Opens: p = ( (y - 1)2 = 12(x - 5) ( , , = ) ) focus: Vertex: directrix: Opens: (x - 3)2 = -8(y + 5) p = ( ( , , = ) ) Find the vertex, focus and directrix of the parabola. Directrix: x2 + 4x - 10y - 6 = 0 Vertex: Focus: ( ( = , , ) ) Write the equation for the parabola in standard form. ( )2 = ( ) ( Find the standard form of the parabola: Vertex: (5, 2) Focus: (9, 2) )2 = ( ) |
