In vertex form:
y = x^2 +8x +16 -16 +18 ('completing the square)
y = (x+4)^2 +2 Vertex h, k = -4,2 Upward opening parabola (coefficient of (x+4)^2 is positive: +1 )
Re-arranging
y-2 = 4p (x+4)^2 4p = 1 p= 1/4 distance from vertex to directrix and focus
Directrix = y= 2- 1/4 = 1.75
Focus = y= 2+1/4 = 2 1/4 x = -4 so -4, 2 1/4
