vertices y=x^2-4x-12

vertices

y = x^{2} - 4 x - 12

Minimum (2, - 16)

Solution steps

y = x^{2} - 4 x - 12

The parabola parameters are:

a = 1, b = - 4, c = - 12

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

x_{v} = - \frac{( - 4 )}{2 \cdot 1}

Simplify

x_{v} = 2

Plug in

x_{v} = 2

to find the

y_{v}

value

y_{v} = - 16

Therefore the parabola vertex is

(2, - 16)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 1

Minimum (2, - 16)

(x + 4)^{2}

f (x) = x^{2} - 6 x - 7

x^{2} - 2 x - 8

x^{2} - 6 x + 10

f (x) = x^{2} + 4 x - 3
