Hi, Previously Posted
x-3=-2((y+4)^2)=3 ??? too many = signs
Anyhow: 4p = -1/2, p = -1/8 Parabola Opens left(-2 < 0) along line of symmetry: y = -4
Need to know the Vertex point..going to guess V(3,-4) ⇒ focus is F(2 7/8, -4)
..............................................................................
the vertex form of a Parabola opening right(a>0) or left(a<0),
where(h,k) is the vertex and y = k is the Line of Symmetry
The standard form is , 0r a = 1/4p, where the focus is (h +p,k ) With Directrix x = (k-p)
