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 vertex of the quadratic equation is (-5, - 28). In vertex form, y = a(x - h)2 + k, (h, k) is the vertex of the equation.
Answer:
The coordinates of the vertex are \((-5,-28)\)
Step-by-step explanation:
we know that
The equation of a vertical parabola into vertex form is equal to
\(f(x)=a(x-h)^{2}+k\)
where
(h,k) is the vertex of the parabola
In this problem we have
\(f(x)=(x+5)^{2}-28\)
\(a=1. h=-5,k=-28\)
therefore
Is a vertical parabola open upward
The vertex is a minimum
The vertex is the point \((-5,-28)\)
