domain of f(x)=sqrt(3/(3+x))

domain

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

x > - 3

Interval Notation

(- 3, \infty)

Solution steps

Find non-negative values for radicals:

x > - 3

Find undefined (singularity) points:

x = - 3

Combine real regions and undefined points for final function domain

x > - 3

y = 5 x + 4

f (x) = (4 - x)

(- 4.2) (1.1)

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

f (x) = \frac{4}{x}
