domain of f(x)=sqrt(7/(3+x))

domain

f (x) = \frac{7}{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 = x^{2} + 2 x - 15

y = 7^{x}

y = \frac{x ^{2}}{x - 8}

\frac{900 - 2 x}{x - 30}

\frac{x}{4 1 - x ^{2}}
