vertices f(x)=-2x^2-16x-37

vertices

Maximum (- 4, - 5)

Solution steps

y = - 2 x^{2} - 16 x - 37

The parabola parameters are:

a = - 2, b = - 16, c = - 37

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

x_{v} = - \frac{( - 16 )}{2 ( - 2 )}

Simplify

x_{v} = - 4

Plug in

x_{v} = - 4

to find the

y_{v}

value

y_{v} = - 5

Therefore the parabola vertex is

(- 4, - 5)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = - 2

Maximum (- 4, - 5)
