vertices f(x)=3x^2+6x-1

vertices

f (x) = 3 x^{2} + 6 x - 1

Minimum (- 1, - 4)

Solution steps

y = 3 x^{2} + 6 x - 1

The parabola parameters are:

a = 3, b = 6, c = - 1

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

x_{v} = - \frac{6}{2 \cdot 3}

Simplify

x_{v} = - 1

Plug in

x_{v} = - 1

to find the

y_{v}

value

y_{v} = - 4

Therefore the parabola vertex is

(- 1, - 4)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 3

Minimum (- 1, - 4)

t^{2} + 2

y = - x^{2} - 4 x + 1

x^{2} - 3 x + 5

3 x^{2} - 3 x

y = 2 x^{2} + 12 x + 17
