range of-x^2-2x+3

Solution

range

- x^{2} - 2 x + 3

Solution

f (x) \leq 4

+1

Solution steps

Vertex of

- x^{2} - 2 x + 3 :

Maximum

(- 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) \leq 4
