Well a rule can come as:

sin(x)/x = "/"
/ \
"sin" x
/
x

Or as follows:

if(x<2,-x,x) = "if"
/ | \
"<" "-" x
/ \ |
x 2 x

if-then-else is also a rule, like any other operation.
The properties continous or differentiable come later.

You define when a function is continous or differentiable,
you don't assume all functions continous and differentiable.
