The answer for the distibutive oneis 7(4+6)
The standard equation of a parabola is:
(y-k) = a(x - h)² , where h and k are the coordinates of the Vertex
Since the vertex is ( - 5 , -7), then :
(y +7) = a (x + 5)².
It's given that the vertex is a minimum, that means the coefficient a>0 and the parabola is open upward.
Depending on the value of a (always a>0) , the equation :
y = a(x-5)² + 7 is a parabola
X=2m-nx-4
