domain of f(x)= 4/(x+7)

domain

f (x) = \frac{4}{x + 7}

x < - 7 or x > - 7

Interval Notation

(- \infty, - 7) \cup (- 7, \infty)

Solution steps

Find undefined (singularity) points:

x = - 7

The function domain

x < - 7 or x > - 7

f (x) = \frac{6}{x + 1}

f (x) = \frac{3 x + 5}{x ^{2} - x - 30}

f (x) = \frac{8}{- 6 - x}

- 1 0^{x + 2} - 3

g (x) = \frac{1}{x ^{2} - x}

What is the domain of f(x)= 4/(x+7) ?
The domain of f(x)= 4/(x+7) is x<-7\lor x>-7
