The standard form for this parabola is [tex]x=a(y-k)^2+h[/tex] because this is a sideways-opening parabola.  Our h and k values for the vertex are (-4, -1).  And it goes through (2,0).  We just need to solve for the a.  Filling in accordingly, [tex]2=a(0+1)^2-4[/tex] so 2 = a - 4.  a = 6.  A above.
