vertices y=9x^2

vertices

y = 9 x^{2}

Minimum (0, 0)

Solution steps

y = 9 x^{2}

The parabola parameters are:

a = 9, b = 0, c = 0

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

x_{v} = - \frac{0}{2 \cdot 9}

Simplify

x_{v} = 0

Plug in

x_{v} = 0

to find the

y_{v}

value

y_{v} = 0

Therefore the parabola vertex is

(0, 0)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 9

Minimum (0, 0)

y = 8 x^{2} + 22 x - 13

y = x^{2} + 8 x + 18

x^{2} - 5 x - 6

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

(x - 1)^{2} = 16 (y - 2)
