range of 2(x+1)^2-3

Solution

range

Solution

f (x) \geq - 3

+1

Interval Notation

Solution steps

Vertex of

2 (x + 1)^{2} - 3 :

Minimum

(- 1, - 3)

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 = 2,

Vertex

(x_{v}, y_{v}) = (- 1, - 3)

f (x) \geq - 3
