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

vertices

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

Minimum (1, 2)

Solution steps

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} = 2

Therefore the parabola vertex is

(1, 2)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = 1

Minimum (1, 2)

9 x^{2} + 16 y^{2} = 144

9 x^{2} + 4 y^{2} = 36

f (x) = x^{2} + 5

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

x^{2} = - 20 y
