domain of y=(x+7)/(x^3+3x^2+3x+1)

domain

y = \frac{x + 7}{x ^{3} + 3 x ^{2} + 3 x + 1}

x < - 1 or x > - 1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

f (x) = \frac{x + 6}{7 x + 6}

f (x) = 5 x^{2} - 5 x - 2

f (x) = \frac{x - 8}{x - 9}

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

h (x) = x + 15
