Should be that i was thinking on the use the arrow operator for a function definition and to use this for graphing this function
It becomes complicated.

the following piecewise-defined function was considered

Strange that this function notation e.g h(1) can be used for a expression ?, while the idea was to use this only for a function defintion with a arrow operator  ( function as a procedure )
Seems to be possible to use the notation e.g : h(1) or h(1.0) if the input parameter is numeric for a expression.

 

The condition in the if statement must be(can only) evaluated numeric..that seems to be not possible with the arrow operator definition in the procedure.

h(x);

Error, (in h) cannot determine if this expression is true or false: x <= 0
