range of f(x)=x^2-2x+5

Solution

range

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

Solution

f (x) \geq 4

+1

Interval Notation

[4, \infty)

Solution steps

Vertex of

x^{2} - 2 x + 5 :

Minimum

(1, 4)

For a parabola

a x^{2} + b x + c

with Vertex

(x_{v}, y_{v})

If

a < 0

the range is

f (x) \leq y_{v}

If

a > 0

the range is

f (x) \geq y_{v}

a = 1,

Vertex

(x_{v}, y_{v}) = (1, 4)

f (x) \geq 4

Popular Examples

domain of f(-2)=2-x domain

f (- 2) = 2 - x

line m=-1,(0,0)line

m = - 1, (0, 0)

domain of f(x)=(4x-3)/(6-5x)domain

f (x) = \frac{4 x - 3}{6 - 5 x}

domain of f(x)=sqrt(x+6)-7 domain

f (x) = x + 6 - 7

inverse of f(x)=3x-3 inverse

f (x) = 3 x - 3
