Question 194519
Name the vertex and axis of symmetry for each quadratic function. Tell wherther the parabola opens up, down, left, or right.
x=2y^2+4y+5
--------------
Since the y^2 term is positive the parabola opens to the right.
-------------------
Complete the square:
2(y^2 + 2y + 1) = x - 5 + 2
2(y+1)^2 = x-3
Vertex: (3,-1)
Axis: y = -1
