Equation in

Question

vertex form y=-(x+5)^2-3 then what's the number of a and h and k

Answer 1

The equation in vertex form is y = a(x-h)^2 + k, where (h,k) is the vertex of the parabola.

Comparing with the given equation y=-(x+5)^2-3, we see that h = -5 and k = -3.

Also, since the coefficient of (x-h)^2 is -1, we can see that a = -1.

Therefore, a = -1, h = -5, and k = -3.
