Equation Vertex Focus Directrix Axis of Symmetry 1. (x-2)2 = 8(y-1) 2. (x+2)2 = 4(y+1) 3. (x +1)2 =-8(y+1) 4. (x+2)2 =-8(y+2) 5. (y+3)2=12(x+1) 6. (y +4)2=12(x+2) 7. (y+1)2 =-8x 8. (y-1)2 =-8x C. Convert each equation to standard form by completing the square on x or y then find the vertex, focus and directrix of the parabola.
