Answer : option A
From the graph
Vertex (-3,1)
Focus (-1,1)
The distance between vertex and focus is P
Distance between vertex and focus = -1 -(-3) = 2
P= 2
General equation for horizontal parabola is
[tex](y-k)^2= 4p(x-h)[/tex]
(h,k) is the vertex
Vertex (-3,1) so h= -3 and k =1, we know p = 2
So equation becomes
[tex](y-1)^2= 4(2)(x-(-3))[/tex]
[tex](y-1)^2= 8(x+3)[/tex]
Answer : option A
