domain of f(x)= 5/(x+7)

domain

f (x) = \frac{5}{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

3 x^{2} + 7 x + 5 D E

f (x) = \frac{4}{x - 1} + 3

f (x) = e^{t} - t

(1.1) (5.5)

f (x) = 2 x^{3} - 15 x^{2} + 36 x + 1

What is the domain of f(x)= 5/(x+7) ?
The domain of f(x)= 5/(x+7) is x<-7\lor x>-7
