vertices-3x^2-5

vertices

Maximum (0, - 5)

Solution steps

y = - 3 x^{2} - 5

The parabola parameters are:

a = - 3, b = 0, c = - 5

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

x_{v} = - \frac{0}{2 ( - 3 )}

Simplify

x_{v} = 0

Plug in

x_{v} = 0

to find the

y_{v}

value

y_{v} = - 5

Therefore the parabola vertex is

(0, - 5)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = - 3

Maximum (0, - 5)
