(–2, 8)

Answer 1

-4

Answer 2

(2,8). need explanation?

Answer 3

yes please

Answer 4

apoork can you give me a explanation please ?

Answer 5

oh yes just a second. if you compare the the equation of this parabola, with the standard equation, y = ax^2+bx+c , you find a,b,c. Now the result for coordinates of the vertex of a parabola are (-b/2a , -D/4a).

here D is the discriminant. D=b^2-4ac
