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

domain

f (x) = \frac{x - 7}{x + 4}

x < - 4 or x > - 4

Interval Notation

(- \infty, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

f (x) = - a \frac{1}{4} (x + 6) - 4

4 - 4 - x

f (x) = 32 (x) - x^{2}

\frac{1 - x}{x}

y = \frac{x ^{2} - 4 x + 4}{x ^{2} - 4}

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