domain of (7x+9)/(x^3+8)

domain

\frac{7 x + 9}{x ^{3} + 8}

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

f (x) = - (x - 6)^{2} + 2

f (x) = - (2^{x - 1})

f (x) = (x - 2)^{2} + Y (x) (x)^{2} = 25

f (x) = 2 x^{2} - 9

f (x) = 2 x - 2 - 3

What is the domain of (7x+9)/(x^3+8) ?
The domain of (7x+9)/(x^3+8) is x<-2\lor x>-2
