The function f(x) = x2 + 10x – 3 written in vertex form is f(x) = (x + 5)2 – 28. what are the coordinates of the vertex?

The coordinates of the vertex are

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

where

(h,k) is the vertex of the parabola

In this problem we have

therefore

Is a vertical parabola open upward

The vertex is a minimum

The vertex is the point

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
