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

domain

f (x) = \frac{7}{x + 9}

x < - 9 or x > - 9

Interval Notation

(- \infty, - 9) \cup (- 9, \infty)

Solution steps

Find undefined (singularity) points:

x = - 9

The function domain

x < - 9 or x > - 9

f (t) = \frac{( 5 t - 1 )}{t + 2}

(ln (x))^{2} + ln (x) - 2

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

f (x) = \frac{3 x + 7}{2} g (x) = x

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

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