Solution

range

Solution

f (x) \leq 9

+1

Interval Notation

Solution steps

Vertex of

- x^{2} + 9 :

Maximum

(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) \leq 9
