vertices x^2+8x+13

vertices

x^{2} + 8 x + 13

Minimum (- 4, - 3)

Solution steps

y = x^{2} + 8 x + 13

The parabola parameters are:

a = 1, b = 8, c = 13

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} = - 3

Therefore the parabola vertex is

(- 4, - 3)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 1

Minimum (- 4, - 3)

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

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

x^{2} + 16 y = 0

+ 3 x^{2} + x + 5

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