Q. Write the equation in vertex form for the parabola with vertex (0,1) and focus (0,3).Simplify any fractions.______
Identify Vertex Form: Identify the vertex form of a vertical parabola.Vertex form: y=a(x−h)2+k
Given Vertex and Focus: Given vertex (h,k)=(0,1) and focus (0,3).Since the focus is above the vertex, the parabola opens upwards.
Calculate Distance for 'a': Calculate the distance between the vertex and focus to find the value of 'a'.Distance = ∣3−1∣=2The distance is the same as 4a1, so 2=4a1.
Solve for 'a': Solve for 'a'.4a1=2a=81
Substitute into Equation: Substitute a, h, and k into the vertex form equation.y=(81)(x−0)2+1y=(81)x2+1
