vertices y=4x^2-16

vertices

Minimum (0, - 16)

Solution steps

y = 4 x^{2} - 16

The parabola parameters are:

a = 4, b = 0, c = - 16

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

x_{v} = - \frac{0}{2 \cdot 4}

Simplify

x_{v} = 0

Plug in

x_{v} = 0

to find the

y_{v}

value

y_{v} = - 16

Therefore the parabola vertex is

(0, - 16)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 4

Minimum (0, - 16)
