vertices f(x)=x^2+6x+9

vertices

f (x) = x^{2} + 6 x + 9

Minimum (- 3, 0)

Solution steps

y = x^{2} + 6 x + 9

The parabola parameters are:

a = 1, b = 6, c = 9

x_{v} = - \frac{b}{2 a}

x_{v} = - \frac{6}{2 \cdot 1}

Simplify

x_{v} = - 3

Plug in

x_{v} = - 3

to find the

y_{v}

value

y_{v} = 0

Therefore the parabola vertex is

(- 3, 0)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 1

Minimum (- 3, 0)
