vertices y=x^2+16x+71

vertices

Minimum (- 8, 7)

Solution steps

y = x^{2} + 16 x + 71

The parabola parameters are:

a = 1, b = 16, c = 71

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

x_{v} = - \frac{16}{2 \cdot 1}

Simplify

x_{v} = - 8

Plug in

x_{v} = - 8

to find the

y_{v}

value

y_{v} = 7

Therefore the parabola vertex is

(- 8, 7)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 1

Minimum (- 8, 7)
