domain of f(x)= 7/(\frac{x){x+7}}

domain

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

x < - 7 or - 7 < x < 0 or x > 0

Interval Notation

(- \infty, - 7) \cup (- 7, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0, x = - 7

The function domain

x < - 7 or - 7 < x < 0 or x > 0

f (x) = \frac{7}{x ^{2} - 36}

y = - x^{2} + 12 x - 38

g (x) = \frac{2}{x ^{2} - 16}

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

\frac{4 ( x - 1 )}{( x + 1 ) ( x - 1 )}

What is the domain of f(x)= 7/(\frac{x){x+7}} ?
The domain of f(x)= 7/(\frac{x){x+7}} is x<-7\lor-7<x<0\lor x>0
