domain of f(x)= x/(x^3+343)

domain

f (x) = \frac{x}{x ^{3} + 343}

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

f (x) = \frac{x ^{2} + 5}{4}

x^{4} - 4 x^{3} + 2 x^{2} + x + 4

f (x) = \frac{2 x + 1}{2 x ^{2} - x - 1}

ln (x - 4)

f (x) = - 3 x + 2 + x + 5

What is the domain of f(x)= x/(x^3+343) ?
The domain of f(x)= x/(x^3+343) is x<-7\lor x>-7
