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

domain

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

7 y - 8 = - 2 (2 - x)

- \frac{3}{2}

(- 1, - 10), (- 9, - 4)

m = 7, (0, 5)

f (x) = \frac{x + 3}{x ^{4} - 81}

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