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

domain

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

f (x) = 20 x - 33

f (x) = 3^{2 - x} - 1

x^{2} + 16 x + 63

f (x) = lo g_{10} (3 x + 2 x - x^{2})

- 2 x^{3} + 18 x^{2} + 49

What is the domain of f(x)=(5x)/(sqrt(x+9)) ?
The domain of f(x)=(5x)/(sqrt(x+9)) is x>-9
