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

domain

f (x) = \frac{x - 7}{x + 5}

x < - 5 or x > - 5

Interval Notation

(- \infty, - 5) \cup (- 5, \infty)

Solution steps

Find undefined (singularity) points:

x = - 5

The function domain

x < - 5 or x > - 5

(x + 4)^{2} - 1

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

\frac{2}{3} sin (6 x)

(6, 4), (- 1, - 3)

f (x) = x 400 - x^{2}

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