domain of f(x)=(x-4)/(x+7)

domain

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

2 + ln (x)

lo g_{10} (x - 5) + 1

f (x) = \frac{1}{x} + ln (x)

f (x) = \frac{8 x}{9 - 2 x}

f (x) = \frac{x}{x ^{2} + 3 x + 5}

What is the domain of f(x)=(x-4)/(x+7) ?
The domain of f(x)=(x-4)/(x+7) is x<-7\lor x>-7
