options
a)y²=-2(x+2)
b)y²=-4(x+3)
c)y²=-6(x-5)

You can put this solution on YOUR website! The parabola opens in the negative x direction.
It has an equation of the form
Where (h,k) are the coordinates of the vertex. p is the distance from the directrix to the vertex or from the focus to the vertex. In this case, p=3
