domain of f(x)= 4/(3+x)

domain

f (x) = \frac{4}{3 + x}

x < - 3 or x > - 3

Interval Notation

(- \infty, - 3) \cup (- 3, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

y = (x + 2)^{2}

x^{3} - 6 x^{2} - 15 x + 3

f (x) = \frac{4}{x - 5}

\frac{1}{x ^{3} + 4 x}

y = \frac{x}{x ^{2} + x - 6}

What is the domain of f(x)= 4/(3+x) ?
The domain of f(x)= 4/(3+x) is x<-3\lor x>-3
