A classic example of a piecewise function is the absolute value function. You may specify the value of a free variable at any point in the equation, but only the first domain specification will be recognized. A piecewise function is a function that is defined on a sequence of intervals. Piecewise functions may reference free variables (a, b, c, etc.), but all pieces must use the same value for each variable. at 16:34 begingroup DonThousand so for example the graph of y (x. You can define piecewise functions of x, y, or theta (polar coordinates), but you may not mix functions of different variables in the same equation. begingroup I mean, as long as the intervals are non-overlapping, and each interval contains a function, then the piecewise function made by combining the functions over each interval is also a function. The graph of a piecewise-defined function may contain internal endcaps if adjacent pieces do not evaluate to the same result at the transition points. To graph a function defined piecewise, we consider each piece of the x x -axis separately. Such a function is said to be defined piecewise. This means that you must specify domains for pieces that abut one another using interval notation so the program can tell which function defines the value for the transition point between the pieces. MFG Piecewise Functions Piecewise Functions A function may be defined by different formulas on different portions of the x x -axis. The domains are not required to span the entire real number line, but they must not overlap. You must specify a domain for each piece, and order the pieces by increasing domain values. Piecewise-Defined Functions - Graphmatica Help. Enter all of the pieces of the equation on the same line, separated by semicolons ( ). Lets graph the piecewise function given in the first section. You can enter Cartesian and polar equations as single-valued piecewise-defined functions. Graphmatica Help - Piecewise-Defined Functions
