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

y = x^{2} + 6 x + 9

f (x) = x - 13

f (x) = x^{4} - 4 x^{2}

(- 1, 7), (6, - 2)

f (x) = \frac{x + 4}{- 2 x - 6}

What is the domain of f(x)=(1/(x+2))-((7x)/(x+2)) ?
The domain of f(x)=(1/(x+2))-((7x)/(x+2)) is x<-2\lor x>-2
