range of f(x)=3x^2-6

Solution

range

f (x) = 3 x^{2} - 6

Solution

f (x) \geq - 6

+1

Interval Notation

[- 6, \infty)

Solution steps

Vertex of

3 x^{2} - 6 :

Minimum

(0, - 6)

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 = 3,

Vertex

(x_{v}, y_{v}) = (0, - 6)

f (x) \geq - 6
