domain of f(x)=(-9x+2)/(x+7)

domain

f (x) = \frac{- 9 x + 2}{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

f (x) = x^{3} + 3 x + 5

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

f (x) = \frac{2}{x - 3} - 1

f (x) = 13 x + 10

(2, - 8), (5, - 6)

What is the domain of f(x)=(-9x+2)/(x+7) ?
The domain of f(x)=(-9x+2)/(x+7) is x<-7\lor x>-7
