Question

Need help in precalculus
Give the coordinates of the vertex and focus and the equation of the parabola
1) y=-2x^2
2) x= -2y^2
3) y=x^2+1
4) x=y^2+1

Answer 1

(x-h)^2 = 4p(y-k),
(y-k)^2 = 4p(x-h), where (h,k) is the vertex and |p| is the distance from the vertex to to focus along the symmetric line
