domain of (x+8)/(x^2+10x+21)

domain

\frac{x + 8}{x ^{2} + 10 x + 21}

x < - 7 or - 7 < x < - 3 or x > - 3

Interval Notation

(- \infty, - 7) \cup (- 7, - 3) \cup (- 3, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3, x = - 7

The function domain

x < - 7 or - 7 < x < - 3 or x > - 3

f (x) = \frac{x + 7}{3}

f (x) = - lo g_{3} (x + 2)

\frac{w}{( w - 1 ) ( w - 2 ) ( w - 3 )}

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

y = \frac{2 x ^{2}}{1 - x ^{2}}
