domain of f(x)= 1/(x-25)

domain

f (x) = \frac{1}{x - 25}

x < 25 or x > 25

Interval Notation

(- \infty, 25) \cup (25, \infty)

Solution steps

Find undefined (singularity) points:

x = 25

The function domain

x < 25 or x > 25

9 x + 1

y = \frac{x ^{2} - 1}{x ^{2} - 4}

f (x) = \frac{2 x + 3}{- 5 x - 53}

f (x) = 2 x^{2} - 6 x + 15

\frac{x}{x + 1} + \frac{1}{x}

What is the domain of f(x)= 1/(x-25) ?
The domain of f(x)= 1/(x-25) is x<25\lor x>25
