vertices-2x^2-4x+3

vertices

Maximum (- 1, 5)

Solution steps

y = - 2 x^{2} - 4 x + 3

The parabola parameters are:

a = - 2, b = - 4, c = 3

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

x_{v} = - \frac{( - 4 )}{2 ( - 2 )}

Simplify

x_{v} = - 1

Plug in

x_{v} = - 1

to find the

y_{v}

value

y_{v} = 5

Therefore the parabola vertex is

(- 1, 5)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = - 2

Maximum (- 1, 5)
