What is the vertex of the graph y = x^2 + 6x - 4?

The vertex of this equation is (-3, - 13)

You can find any vertex by first looking for the x value. You can find the x value by using the following equation.

-b/2a

In this equation, 'a' refers to the coefficient of x^2 (1) and 'b' refers to the coefficient of x (6). So we can use these numbers to find the x value.

-b/2a

- (6) / 2 (1)

-6/2

-3

Now that we have the x value, we can substitute the value in for x and solve for the y value.

x^2 + 6x - 4

(-3) ^2 + 6 (-3) - 4

9 - 18 - 4

-13

And this gives you the ordered pair of (-3, - 13)
