vertices y=x^2+4

vertices

y = x^{2} + 4

Minimum (0, 4)

Solution steps

y = x^{2} + 4

The parabola parameters are:

a = 1, b = 0, c = 4

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

x_{v} = - \frac{0}{2 \cdot 1}

Simplify

x_{v} = 0

Plug in

x_{v} = 0

to find the

y_{v}

value

y_{v} = 4

Therefore the parabola vertex is

(0, 4)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 1

Minimum (0, 4)

x^{2} - 6 x + 5

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

f (x) = - x^{2} - 2 x + 8

- x^{2} + 6 x - 5

y = x^{2} - 9 x + 20
