domain of ((x+5))/(x^2-25)

domain

\frac{( x + 5 )}{x ^{2} - 25}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 5, x = - 5

The function domain

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

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

f (x) = (x)

x 2 - x^{2}

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

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

What is the domain of ((x+5))/(x^2-25) ?
The domain of ((x+5))/(x^2-25) is x<-5\lor-5<x<5\lor x>5
