vertices 2(x-1)^2+1

vertices

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

Minimum (1, 1)

Solution steps

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

Rewrite

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

in the form

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

y = 2 x^{2} - 4 x + 3

The parabola parameters are:

a = 2, b = - 4, c = 3

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

x_{v} = - \frac{( - 4 )}{2 \cdot 2}

Simplify

x_{v} = 1

Plug in

x_{v} = 1

to find the

y_{v}

value

y_{v} = 1

Therefore the parabola vertex is

(1, 1)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 2

Minimum (1, 1)

f (x) = (x - 7)^{2} - 1

x^{2} + 6 x + 8 y = 7

x^{2} - 6 x + 5 y = - 34

x^{2} + 2 x

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