domain of g(x)= 3/(x^2-2x-15)

domain

g (x) = \frac{3}{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

- 4 n \cdot \frac{x ln ( x )}{1 - x}

g (x) = 5 - x + 1

arcsin (2 x)

f (x) = \frac{1}{1.6 x - 3.4 x ^{2}}

5 x + 4

What is the domain of g(x)= 3/(x^2-2x-15) ?
The domain of g(x)= 3/(x^2-2x-15) is x<-3\lor-3<x<5\lor x>5
