The equation is in vertex form,
where (h,k) is the vertex.
(h,k)=(4,-9)
Answer by nyc_function(2741) (Show Source): You can put this solution on YOUR website!
Your equation is of the form y = a(x - h)^2 + k.
The vertex is the point (h,k).
You were given f(x) = 6(x - 4)2 - 9.
Plugging -4 and -9 into the formula above, we learn that the vertex is
the point (4, -9).
Done!
