What is the vertex of the graph of the function below? y=x^2+6x+5

y = x² + 6x + 5

Use the formula: - b/2a

a = 1

b = 6

- 6 / 2

= - 3

The x-coordinate of the vertex is - 3

Plug the x value back into the original equation to find the y-coordinate of the vertex

y = (-3) ² + 6 (-3) + 5

y = - 4

Answer: (-3,-4)
