domain of f(x)= 3/(x-7)

domain

f (x) = \frac{3}{x - 7}

x < 7 or x > 7

Interval Notation

(- \infty, 7) \cup (7, \infty)

Solution steps

Find undefined (singularity) points:

x = 7

The function domain

x < 7 or x > 7

p = 15 n + 300

x - 1 + 3

2 x - 3

f (x) = \frac{4 x - 36 x}{3 x - 27}

\frac{1}{x - 5}

What is the domain of f(x)= 3/(x-7) ?
The domain of f(x)= 3/(x-7) is x<7\lor x>7
