For finding the equation of parabola at vertices we use the general equation of parabola at vertices point (h,k) is given
y=a(x-h)^2+k…….(1)
The vertex of the parabola equation is at point (5, -3) by equation (1)
y=a(x-5)^2-3
We can't find the value of a because in the question we don't have any information about “a” so option C is correct.
y=-3(x-5)^2-3.
