domain of (sqrt(x+9))/(sqrt(x+8))

domain

\frac{x + 9}{x + 8}

x > - 8

Interval Notation

(- 8, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 8

Find undefined (singularity) points:

x = - 8

Combine real regions and undefined points for final function domain

x > - 8

x - 2 y = - 10

f (x) = 25 - x^{2}

f (x) = 9 x^{2} - x^{3} - 3

f (x) = \frac{1}{x} + 3 x
