If (x+5=0 ) is the directrix and ((-3,0) ) the vertex of a parabola, then equation of this parabola is ____

Options

  1. A(y^2=8(x+3) )
  2. B(y^2=8(x-3) )
  3. C(x^2=8(y+3) )
  4. D(x^2=8(y-3) )

Correct answer

A. (y^2=8(x+3) )

Step-by-step solution

Given parabola is, So, its equation is, (y^2=4 a(x-(-3) ) Where (a=2 ) units. ( y^2=8(x+3) )
