Depending on the function, it can have any value whatsoever.
The graph of a continuous function will not have any 'breaks' or 'gaps' in it. You can draw it without lifting your pencil or pen. The graph of a discrete function will just be a set of lines.
y=x+1
An intuitive answer (NOTE: this is far from precise!) A function is continuous if you can trace its graph without lifting your pencil from the page. If, additionally, it is smooth everywhere without any jagged edges or abrupt corners, then it is differentiable. It is not possible for a function to be differentiable but not continuous. On the other hand, plenty of functions are continuous without being differentiable.
The function round requires another parameter which indicated the degree to which the number is to be rounded. Without it the function has no meaning.
can a computer function/work without ac current
would we be able to function in society without rules
Primary markets can not function well without secondary markets
Without any function is impossible. So I'll assume you mean any coded function, in which case the predefined function below is your answer.$string = strrev($string);
