range of 2x^2-8x-3

Solution

range

2 x^{2} - 8 x - 3

Solution

f (x) \geq - 11

+1

Interval Notation

[- 11, \infty)

Solution steps

Vertex of

2 x^{2} - 8 x - 3 :

Minimum

(2, - 11)

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}) = (2, - 11)

f (x) \geq - 11
