Answer:
y = 1/4x^1 -x -4
Step-by-step explanation:
Same question as previous parts. The working is identical, using different numbers.
Focus-vertex distance is (y-difference) p = -4-(-5) = 1. Vertex is (h, k) = (2, -5). Putting these values into the vertex form and expanding to standard form, you get ...
y = (1/(4p))(x -h)^2 +k
y = 1/4(x -2)^2 -5 . . . . . . . . fill in the values for p, h, k
y = 1/4(x^2 -4x +4) -5 . . . . expand the square
y = 1/4x^2 -x +1 -5 . . . . . . . use the distributive property to eliminate parens
y = 1/4x^1 -x -4 . . . . . . . . . collect terms
