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

f (x) = \frac{x ^{2} + 5 x}{2 x ^{2} + 7 x - 15}

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

y = - x^{2} - 2 x - 2

f (x) = x^{2} + 3 x - 2

4 y = 3 x + 2

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