Step-by-step explanation:

Given

Required

Equation of the parabola (in standard form)

The standard form of a parabola is

Such that

Vertex = (h,k)

Focus = (h, k + p)

For the vertex

This implies that (h,k) = (0,0)

h = 0 and k = 0

For the focus

This implies that (h, k + p) = (0, -4)

Recall that

Hence,

Substitute , in the given formula

becomes

Hence,, the standard form is

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
