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

vertices

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

Minimum (- \frac{3}{4}, - \frac{25}{8})

Solution steps

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

The parabola parameters are:

a = 2, b = 3, c = - 2

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

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

Simplify

x_{v} = - \frac{3}{4}

Plug in

x_{v} = - \frac{3}{4}

to find the

y_{v}

value

y_{v} = - \frac{25}{8}

Therefore the parabola vertex is

(- \frac{3}{4}, - \frac{25}{8})

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 2

Minimum (- \frac{3}{4}, - \frac{25}{8})

f (x) = x^{2} + 10 x + 21

y = (9 x - 2) x 3

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

f (x) = x^{2} - 4 x + 1

y = 3 x^{2} + 5 x - 4
