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

domain

f (x) = \frac{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

in v erse f (x) = \frac{2 x - 3}{5 x - 1}

d o main f (x) = \frac{x}{7}

in v erse f (x) = 9 + (5 x + 9)^{3}

d o main 3 1 + ∣ x ∣ - 3

d o main f (x) = (2 x + 3) x^{2} + 8

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