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

vertices

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

Minimum (- \frac{3}{2}, - \frac{11}{2})

Solution steps

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

The parabola parameters are:

a = 2, b = 6, c = - 1

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

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

Simplify

- \frac{6}{2 \cdot 2} : - \frac{3}{2}

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

Plug in

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

to find the

y_{v}

value

y_{v} = - \frac{11}{2}

Therefore the parabola vertex is

(- \frac{3}{2}, - \frac{11}{2})

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 2

Minimum (- \frac{3}{2}, - \frac{11}{2})

y^{2} = 12 x

x^{2} + 6 x + 5

y = 3 x^{2} - 5 x 7

y^{2} = - 8 x

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