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

domain

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

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

3 x^{5} + 5 x^{4}

\frac{1 - 5 x}{x ^{2} + 4}

3 - x

\frac{x}{1 - x}

g (x) = 2 x + 3

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