domain of f(x)=(x^3+27)/(x+3)

domain

f (x) = \frac{x ^{3} + 27}{x + 3}

x < - 3 or x > - 3

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

f (x) = (- \frac{16}{( 3 + t ) ^{2}})

\frac{x - 2}{x ^{2} + 5 x + 4}

f (x) = 2 x - 1

(- 4, 2), (4, 2)

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

What is the domain of f(x)=(x^3+27)/(x+3) ?
The domain of f(x)=(x^3+27)/(x+3) is x<-3\lor x>-3
