Answer:

y= 1/12(x-0)^2+0

this answer works as an upward parabola

Step-by-step explanation:

  • The formula for a veritcal parabola is y=1/4p(x-h)^2+k
  • (h,k)= coordinates of the vertex of the parabola
  • p= absolute value of the distance from the vertex to the focus/directrix
  • In this problem, it is given that the vertex is at the origin (0,0) and the focus (the bulb), is 3 centimeters away from the vertex.
  • Now, you know the values of the variables. Fill in the values
  • FROM THE FORMULA: 1/4p turns into 1/12 since p is 3.
  • (x-h)^2+k turns into (x-0)^2+0, since h and k where the values of the vertex which was 0,0
  • once all the variables are given values (except x and y) you have made your equation!
  • The answer is y=1/12(x-0)^2+0
