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

domain

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

x > - 1

Interval Notation

(- 1, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 1

Find undefined (singularity) points:

x = - 1

Combine real regions and undefined points for final function domain

x > - 1

f (x) = ln (e^{x + 1}) + ln (2) - 1

(8.2) (3.8)

f (x) = \frac{1}{x - 2} - 3

tan (\frac{π x}{4} + \frac{3 π}{4})

3 (x + 5) + 4

What is the domain of f(x)= 4/(sqrt(x+1)) ?
The domain of f(x)= 4/(sqrt(x+1)) is x>-1
