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

Solution

range

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

Solution

f (x) \geq - 2

+1

Solution steps

Vertex of

x^{2} - 2 :

Minimum

(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) \geq - 2
