domain of ((x+8))/((x^2-2x-15))

domain

\frac{( x + 8 )}{( x ^{2} - 2 x - 15 )}

x < - 3 or - 3 < x < 5 or x > 5

Interval Notation

(- \infty, - 3) \cup (- 3, 5) \cup (5, \infty)

Solution steps

Find undefined (singularity) points:

x = 5, x = - 3

The function domain

x < - 3 or - 3 < x < 5 or x > 5

f (x) = \frac{1}{4 - 2 - x}

f (x) = - x^{2} - 3 x + 4

f (x) = \frac{x - 1}{x ^{2} + 6 x - 27}

y = \frac{x + 1}{2 x + 1}

f (x) = ∣ x ∣ - x
