domain of f(x)=sqrt((x+2)/(x^2-(-9)))

domain

f (x) = \frac{x + 2}{x ^{2} - ( - 9 )}

x \geq - 2

Interval Notation

Solution steps

Find non-negative values for radicals:

x \geq - 2

The function domain

x \geq - 2

f (x) = - 2 (x - 4)^{2} + 1

2 x^{2} + 3 x + 4

- 35 - 18 x

f (x) = 3 x^{2} + 4 x + 1

\frac{2 x ^{2} + x}{x ^{2} - 5 x + 6}
