Question

Write an equation of a parabola with the given vertex and focus.
vertex (-1,3); focus (-1,4)

Answer 1

Answer: (x + 1) ^2 = 4(y – 3)

Explanation: The equation of a parabola with vertex (h,k) and focus (h, k +p) is given by (x – h)^2 = 4p(y – k). In this case, the vertex is (-1,3) and the focus is (-1,4), so the equation would be (x + 1)^2 = 4(y-3).
