domain of f(x)=(1/(x+2))-((7x)/(x+2))

domain

f (x) = (\frac{1}{x + 2}) - (\frac{7 x}{x + 2})

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

What is the domain of f(x)=(1/(x+2))-((7x)/(x+2)) ?
