vertices x^2-3x-10

vertices

x^{2} - 3 x - 10

Minimum (\frac{3}{2}, - \frac{49}{4})

Solution steps

y = x^{2} - 3 x - 10

The parabola parameters are:

a = 1, b = - 3, c = - 10

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

x_{v} = - \frac{( - 3 )}{2 \cdot 1}

Simplify

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

Plug in

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

to find the

y_{v}

value

y_{v} = - \frac{49}{4}

Therefore the parabola vertex is

(\frac{3}{2}, - \frac{49}{4})

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 1

Minimum (\frac{3}{2}, - \frac{49}{4})

y = 4 x^{2}

3 x^{2}

x^{2} + 8 x - 5

+ 7 x^{2} + 5

y = 6 x^{2} - 3 x 5
