domain of f(x)= 4/(x-7)

domain

f (x) = \frac{4}{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

\frac{4}{x + 4} + x + 1

(5, - 9), (- 9, 13)

f (x) = x^{2} + 5 x - 14

(\frac{1}{2})^{x - 7}

\frac{1}{4}

What is the domain of f(x)= 4/(x-7) ?
The domain of f(x)= 4/(x-7) is x<7\lor x>7
