Question

Equation for parabola vertex (-4,-1) focus (0,-1)

Answer 1

solution's Here v = (-4,-1) & F=60-1) By using short technique. Here y co-ordinates of vertex and focous are same. so the ean of parabola is (y-k)? = 4p (ze-h) - 0 where u= (hik)= (-4,-1) F = (h+p, k) = (01-1) K= -1 h = -4 P= (htp)- = 0-(-4) P = 4 putting all values of b, p and k in equation © we get, (4-(-1))? = 419) (2-(-4)). (y +1)2 = 16 (x +4) [+)2 = 16 3 +64 this is the equired equation.
