domain of f(x)=(4x)/(x^2+2x-15)

domain

f (x) = \frac{4 x}{x ^{2} + 2 x - 15}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 3, x = - 5

The function domain

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

3 x^{3} + 4 x^{2} - x - 4

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

f (x) = \frac{3 x - 2}{x ^{3} - 1}

y + 5 = - x + 1

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

What is the domain of f(x)=(4x)/(x^2+2x-15) ?
The domain of f(x)=(4x)/(x^2+2x-15) is x<-5\lor-5<x<3\lor x>3
