I have finished the first two steps to this and shown my work (in bold) and answers below (in bold). I am stuck on Step 3 however. Part II:

I have finished the first two steps to this and shown my work (in bold) and answers below (in bold). I am stuck on Step 3 however.

Part II:x

Step 1:x

Vertex = 1/4(y-4)^2+2

Vertex = (2,4)

Step 2:hpkhpk

hpk4p(x-h) = (y-k)^2

xhp   4(x-2) = (y-4)^2

hk

h = 2

p = 1

k = 4

Step 3: Horizontal parabolas can be modeled by the equation (y-k)^2 = 4p(x-h). Use the information from Step 2 to write the equation for 

the cross section of Raj's flashlight. Simplify your answer by writing the equation in standard form, x=ay^2+by=c. Show work.
