vertices 2x^2-6x+4

vertices

2 x^{2} - 6 x + 4

Minimum (\frac{3}{2}, - \frac{1}{2})

Solution steps

y = 2 x^{2} - 6 x + 4

The parabola parameters are:

a = 2, b = - 6, c = 4

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{1}{2}

Therefore the parabola vertex is

(\frac{3}{2}, - \frac{1}{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{1}{2})

f (x) = - 3 x^{2} - 18 x + 2

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

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

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

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