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

Solution

range

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

Solution

f (x) \leq - 2

+1

Interval Notation

(- \infty, - 2]

Solution steps

Vertex of

- 2 - x^{2} :

Maximum

(0, - 2)

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}) = (0, - 2)

f (x) \leq - 2
