Under Â§ 1505, however, a defendant can be convicted of obstruction of justice by obstructing a pending proceeding before Congress or a federal agency. A pending proceeding could include an informal investigation by an executive agency.
Piecewise is actually a way of expressing the function, rather than a characteristic of the function itself, but with additional qualification, it can describe the nature of the function.
Piecewise functions are functions that have more than one part, the most common of which is the absolute value function. Each piece of the function has a well-defined domain, or x-value. To graph a piecewise function, you need only to be sure that you have properly defined the area for each graph and then only place the graph in that area.
