Question

What is the vertex of `y= x^2 - 2x - 15`?

Answer 1

Vertex is at `(1,-16)`

Explanation:

`y=x^2-2x-15 or y= (x-1)^2-16` We know, equation of parabola in vertex form is `y=a(x-h)^2+k` where `(h,k)` is the vertex. So here the vertex is at `(1,-16)` graph{x^2-2x-15 [-40, 40, -20, 20]}[Ans]
