24 - 0.25 (x - (- 9))^{2} > 11.75

- 16 < x < - 2

Interval Notation

(- 16, - 2)

Solution steps

24 - 0.25 (x - (- 9))^{2} > 11.75

Multiply both sides by

100

2400 - 25 (x - (- 9))^{2} > 1175

Move

2400

to the right side

- 25 (x - (- 9))^{2} > - 1225

Multiply both sides by

- 1

25 (x - (- 9))^{2} < 1225

Divide both sides by

25

(x - (- 9))^{2} < 49

For

u^{n} < a

, if

n

is even then

- 49 < x - (- 9) < 49

a < u < b

then

a < u and u < b

- 49 < x - (- 9) and x - (- 9) < 49

- 49 < x - (- 9) : x > - 16

x - (- 9) < 49 : x < - 2
