Find the Numbers at Which F Is Continuous $$f ( x ) = \left\{ \begin{aligned}x - 5 & \text { if } x \leq 5 \\2 x - 10 & \text { if } x > 5\end{aligned} \right.$$

Multiple Choice

Find the numbers at which f is continuous. At which numbers is f discontinuous?
- $$f ( x ) = \left\{ \begin{aligned}x - 5 & \text { if } x \leq 5 \\2 x - 10 & \text { if } x > 5\end{aligned} \right.$$

A) continuous for all real numbers except $x = - 5 , x = 5$
B) continuous for all real numbers except $x = 5$
C) continuous for all real numbers
D) continuous for all real numbers except $x = 0$
