domain of f(x)=(x^2-16)/(x^2-25)

domain

f (x) = \frac{x ^{2} - 16}{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

\frac{2 x - 6}{x ^{2} + 7 - 4}

\frac{1}{x - 1} - 1

f (x) = \frac{x ^{3} - 2 x ^{2} - 3 x}{2 x ^{2} - x - 6}

f (x) = (x + 3)^{2} + (y + 6)^{2} = 16

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

What is the domain of f(x)=(x^2-16)/(x^2-25) ?
The domain of f(x)=(x^2-16)/(x^2-25) is x<-5\lor-5<x<5\lor x>5
