Find the numbers at which f is continuous. At which numbers is f discontinuous?
-$$f ( x ) = 3 x - 1$$
A) continuous for all real numbers
B) continuous for all real numbers except $x = 1$
C) continuous for all real numbers except $x = \frac { 1 } { 3 }$
D) continuous for all real numbers except $x = - \frac { 1 } { 3 }$

The function $f(x) = 3x - 1$ is a linear function, which is continuous at every point in its domain. Since the domain of a linear function is all real numbers, $f(x)$ is continuous for all real numbers.
