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

domain

f (x) = \frac{x}{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

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

\frac{1}{x - 2}

\frac{3}{( x + 3 ) ^{2}}

(- 2, - 5), (- 1, - 3)

(- 4, 2), (- 2, - 5)

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