domain of f(x)= 5/(sqrt(x+9))

domain

f (x) = \frac{5}{x + 9}

x > - 9

Interval Notation

(- 9, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 9

Find undefined (singularity) points:

x = - 9

Combine real regions and undefined points for final function domain

x > - 9

3 x + y = 9

f (x) = 7 x^{3} + 8

- x^{2} + 10 x - 21

(- 6, - 2), (3, - 8)
