vertices x^2+8x+12

vertices

x^{2} + 8 x + 12

Minimum (- 4, - 4)

Solution steps

y = x^{2} + 8 x + 12

The parabola parameters are:

a = 1, b = 8, c = 12

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

x_{v} = - \frac{8}{2 \cdot 1}

Simplify

x_{v} = - 4

Plug in

x_{v} = - 4

to find the

y_{v}

value

y_{v} = - 4

Therefore the parabola vertex is

(- 4, - 4)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 1

Minimum (- 4, - 4)

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

f (x) = x^{2} - 8 x

+ 3 x^{2} + x + 5

y = 3 x^{2} + x - 1

28 x^{2} + 47 x + 15
