vertices f(x)=(x-3)^2-1

vertices

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

Minimum (3, - 1)

Solution steps

y = (x - 3)^{2} - 1

Rewrite

y = (x - 3)^{2} - 1

in the form

y = a x^{2} + b x + c

y = x^{2} - 6 x + 8

The parabola parameters are:

a = 1, b = - 6, c = 8

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

x_{v} = - \frac{( - 6 )}{2 \cdot 1}

Simplify

x_{v} = 3

Plug in

x_{v} = 3

to find the

y_{v}

value

y_{v} = - 1

Therefore the parabola vertex is

(3, - 1)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 1

Minimum (3, - 1)

f (x) = x^{2} + 6 x + 7

y = 2 x^{2} - 12 x + 23

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

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

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