vertices f(x)=(x-1)^2-4

vertices

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

Minimum (1, - 4)

Solution steps

y = (x - 1)^{2} - 4

Rewrite

y = (x - 1)^{2} - 4

in the form

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

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

The parabola parameters are:

a = 1, b = - 2, c = - 3

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

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

Simplify

x_{v} = 1

Plug in

x_{v} = 1

to find the

y_{v}

value

y_{v} = - 4

Therefore the parabola vertex is

(1, - 4)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 1

Minimum (1, - 4)

x^{2} - x - 20

x^{2} - 8 x + 9

x^{2} - 8 x + 7

x^{2} + 16

y = x^{2} + 4 x
