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

domain

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

x < - 4 or x > - 4

Interval Notation

(- \infty, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

f (x) = 7 ln (x)

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

y = \frac{1}{2} x + 3

f (x) = - \frac{4}{x ^{2} - 3 x}

17 - x^{6}

What is the domain of f(x)= 4/(4+x) ?
The domain of f(x)= 4/(4+x) is x<-4\lor x>-4
