Q. Write the equation in vertex form for the parabola with vertex (0,4) and focus (0,7).Simplify any fractions.______
Identify Orientation: Identify the orientation of the parabola based on the vertex and focus.Since the vertex and focus have the same x-coordinate, the parabola is vertical.
Determine Opening Direction: Determine the direction the parabola opens.The focus (0,7) is above the vertex (0,4), so the parabola opens upwards.
Calculate Distance for 'a': Calculate the distance between the vertex and the focus to find the value of 'a'.Distance = ∣7−4∣=3The value of 'a' is 4⋅31 because the parabola opens upwards.
Write Vertex Form: Write the vertex form of the equation using the vertex (h,k)=(0,4) and the value of ′a′. y=a(x−h)2+ky=121(x−0)2+4y=121x2+4
