domain of f(x)= 1/(sqrt(4+x))

domain

f (x) = \frac{1}{4 + x}

x > - 4

Interval Notation

(- 4, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 4

Find undefined (singularity) points:

x = - 4

Combine real regions and undefined points for final function domain

x > - 4

in v erse f (x) = \frac{5}{6} x + \frac{5}{3}

d o main \frac{2 x}{1 - 5 x}

l in e - x - 1

p er i o d i c i t y 105 - 20 sin (\frac{5 π}{4} x)

in v erse - \frac{5}{x}
