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

domain

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

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) = \frac{1}{2} cot (π x)

3

y = x^{2} - 4 x + 5

y = (x - 6)^{2}

f (x) = lo g_{4} (x + 1)

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