domain of f(x)=(x-4)/(x+3)

domain

f (x) = \frac{x - 4}{x + 3}

x < - 3 or x > - 3

Interval Notation

(- \infty, - 3) \cup (- 3, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

f (x) = \frac{x}{1 - ∣ x ∣}

f (x) = ln (50 - x^{2})

\frac{x + 2}{x ^{2} - 3 x - 10}

f (y) = \frac{1}{( y - 2 ) + ( y - 8 )}

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

What is the domain of f(x)=(x-4)/(x+3) ?
The domain of f(x)=(x-4)/(x+3) is x<-3\lor x>-3
