range of x^2-9

Solution

range

x^{2} - 9

Solution

f (x) \geq - 9

+1

Solution steps

Vertex of

x^{2} - 9 :

Minimum

(0, - 9)

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, - 9)

f (x) \geq - 9
