domain of f(x)=(x^2-25)/(x-5)

domain

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

x < 5 or x > 5

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 5

The function domain

x < 5 or x > 5

f (x) = 4 x + 52

\frac{1}{x} + 10

\frac{x ^{2} - 4}{2 x ^{2}}

f (x) = \frac{6}{x + 4} - \frac{1}{2 - x}

f (x) = - ln (x + 1)

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